Abstract
A track and flap assembly includes a brake section and terminates with a curved section and a support member, for guiding a cutting tape transversely across a moving web of paper, and employs a plurality of movable sections enabling relocation of the brake section, and the curved section and its support member without changing their configuration to accommodate different trim widths of the web. The assembly includes a track that has an open channel containing the cutting tape and at least one flap for frictionally engaging the cutting tape when the tape exits laterally from the channel to assist in controlling the tension thereon and its movement. A pair of flaps may extend over a portion of the channel less than the entire width of the channel, and a third flap may overlie and at least cover the space between the pair of flaps forming a complete seal therein. A single flap may form with the channel the top of the guideway for the tape. The pair of flaps may also control the exit direction of the cutting tape from the curved section with one such flap being more pliable and longer than the other. The track includes compressed air or coolant to keep the channel free of contaminants and control its temperature or a liquid coolant to just control its temperature.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a track assembly for cutting tape used in turn up operations in the papermaking industry and particularly to a track assembly having removable sections to enable adjustment of the track assembly to different trim widths of paper spools.
2. Related Art
A few track assemblies known in the art are disclosed in Applicant's U.S. Pat. Nos. 4,659,029; 4,783,018; 5,046,675; and Applicant's U.S. application Ser. No. 09/421,702 filed on Oct. 20, 1999, now U.S. Pat. No. 6,305,634 on an improved track and flap assembly for cutting tape. Those track assemblies have a channel through which the tape moves and includes a brake section secured to the channel to frictionally engage the tape to control its movement. The channel terminates with a curved section supported by a supporting member and has a particular configuration for directing a cutting tape to attach to an empty spool. On occasions, the locations of the brake and the curved section with its supporting member need to be adjusted to accommodate for different trim widths of various spools of paper used in the papermaking industry. The trim width of a spool is the distance between a proximate end to a distal end of the spool, which is always less than the length of paper wrapped around the spool. In order to change the locations of the brake and the curved section, the assembly track must be taken apart to relocate the brake section and to move the curved section, and then reassembled. Those actions change the configuration of the curved section and its supporting member, which needs to be readjusted every time for every trim width. Accordingly, there is a need for a track assembly that permits relocation of the brake position and the curved section without changing the configuration of the curved section and its supporting member.
A primary function of the track assembly is to guide a cutting tape transversely across a moving web of paper being wound on a spool and transferring a web onto an empty spool by attaching a tape to an empty spool. In order to control the movement of the cutting tape that exits laterally from the channel, a brake section is used to frictionally engage the tape to reduce its speed. Applicant's U.S. Pat. No. 6,305,634 provides a track and flap assembly that includes a compressible means or a foam material extending transversely over the channel to provide a controlled resistance against the cutting tape exiting to assist in control of the tape spooling on an empty spool. A plurality of flap members can be positioned between the foam material and the channel to provide for additional friction when the tape exits the channel. However, the occasional frictional wear between the foam block and the flap members is an undesirable effect. Accordingly, there is a need for a controlled resistance of the tape that has less frictional wear.
Additionally, the channel often gets contaminated from the surrounding environment. In order to prevent contamination, Applicant's U.S. Pat. No. 6,305,634 provides a track and flap assembly that includes an air hose that directs air via passageway into the channel to inhibit contamination since contaminants may adversely affect the introduction of the tape through the guideway or channel, particularly since the adhesive is applied to the cutting tape and slides with its bottom adjacent the contact surface of the guideway picking up debris with the adhesive that adversely affects its adherence to the empty spool. However, air wasn't provided throughout the entire track by the air hose. Accordingly, there is a need for a method for supplying air throughout the entire track to keep the track free from contaminants.
Furthermore, the channel often becomes heated due to the ambient condition of the location of the turn-up assembly adjacent the heated drier end of the paper making machines, these could be a pulper located beneath the paper reel and steam is added to such pulper causing increased heat and humidity and creating additional problems for the cutting tape traveling through the guideway. The prior art does not disclose or suggest a method for controlling the temperature of the channel. Accordingly, there is a need for a method for controlling the temperature of the channel.
The present invention provides for removable sections of the track, including brake means section, to enable addition, deletion or relocation of the brake means with respect to any variable trim width of a paper spool, and to enable relocation of the curved section and the supporting member along the track without changing their configuration.
The present invention also provides for a controlled resistance against the cutting tape through a single flap, double or triple flaps mounted on top of the channel to engage the tape when laterally exiting from the channel. Customizing of the frictional brake effect of the flaps may be achieved which are primarily dictated by machine speed, grade and calipers of the web.
Another embodiment of the present invention provides for a plurality of compressible means or flap members covering different portions of the channel. One flap member is secured to one side of the channel extending over a portion of the channel substantially less than the width of the channel. Another flap member is secured to the other side of the channel directly opposite from the one flap member and covering less than a substantial width of the channel without touching the other flap to minimize frictional wear between them. In order to provide for an enlarged seal of the channel to inhibit entry of contaminants into the channel from the surrounding environment and to assist in controlling the lateral movement of the cutting tape, a third flap member is secured to one side of the channel juxtaposed to and on top of the one flap member and extending substantially over the channel forming a complete seal therein.
The present invention provides a method for keeping the channel free from contaminants from the surroundings by supplying air to the entire channel by a plurality of air passages throughout the entire track located below the upper portion of the track and a respective number of passageways to fluidly communicate between the air passages and the channel. The distribution of air throughout the entire track by the air passages helps keep the cutting tape afloat by the positive pressure of the supplied air and thereby reducing friction between the tape and the channel.
A coolant can be pumped through the passages to help control the temperature of the channel, which is heated by the ambient conditions of the location of the turn-up assembly.
It is an object of the present invention to provide for a track assembly having a readily movable and adjustable brake section.
It is another object of the present invention to provide for a track assembly having readily movable and adjustable curved section and its supporting member that maintain their configuration.
It is another object of the present invention to provide for a track assembly having adjustable and movable brake and curved sections to accommodate for different web trim widths.
Still, it is a further object of the present invention to provide for a track assembly having flap means covering different portions of the channel to assist in controlling a tape exiting laterally from the channel.
It is a related object of the present invention to provide for a track assembly having a single flap member extending substantially over the channel to provide for frictional engagement with the tape.
It is a further object of the present invention to provide for a track assembly having a track including upper and lower portions and having a channel in the upper portion throughwhich a cutting tape moves, a plurality of spaced elongated air passages through the entire track located below the upper portion, a plurality of spaced passageways communicating fluidly between the passages and the channel for receiving compressed air to control the temperature of the channel and to keep the channel clean from contaminants.
Yet, it is another object of the present invention to provide for a track having an upper portion and having coolant passage located below the upper portion of the track for receiving a coolant at a lower temperature than the channel to control the temperature of the channel, which is frictionally heated by a cutting tape passing therethrough. Still other objects of the present invention will become apparent from the more detailed description that follows.
BRIEF SUMMARY OF THE INVENTION
The present invention relates to an improved track assembly for guiding a cutting tape transversely across a moving web of paper being wound on a spool and transferring the cut web to an empty spool. The assembly includes an elongated fixed track support extending beyond the edge of a web and an elongated track having opposite ends adjacent side edges of a moving web for receiving a cutting tape into one open end and exiting out of the other open end. The track has upper and lower portions and a longitudinal channel or guideway formed in the upper portion throughwhich the cutting tape moves. Flap means including, in one embodiment of the present invention first and second elongated flap means, each being fastened to one side of the upper portion directly opposite from each other and extending toward each other, covering a portion of the channel. A third elongated flap means extends substantially over the channel and is disposed on top of the first and second flap means to form a complete seal therewith to assist in controlling the cutting tape exiting laterally from the channel to attach to an empty spool.
The flap means can be selected to increase or decrease tension in the cutting tape as it is being pulled out from the track. For example, varying the space covered by the flap means over the open channel may vary such tension, but debris is more likely to enter. Also, varying the pliability of the flap means changes the tension. The position of the flap means can also be selected so that more or less tension is applied at different portions along the track. The present invention provides softer flap means than the guideway of the prior art and as a consequence the flap means do not damage the edges of the cutting tape as it is being pulled out of the guideway. The track further includes a track carrier that has an elongated hollow and an upper portion for carrying the track. The track carrier is mounted on the elongated fixed support extending through the hollow.
Another embodiment of the present invention further includes a curved section positioned at the other open end of the track having a configuration for inverting the cutting tape to position an adhesive carried by the cutting tape upwardly and to be fed to a nip formed between the empty spool and a web driving spool, and supporting member for supporting the curved section and is slidably movable along the support. The curved section typically includes a pair of elongated flap means extending over the guideway to control the exit of the cutting tape. The exit direction of the tape can be controlled by making one flap means more pliable and longer than the other flap means, thereby permitting the cutting tape to exit laterally adjacent the less pliable flap means. The track also includes a brake means section detachably mounted on the track for frictionally engaging the tape. The track having a plurality of movable sections in proximity with the brake means section enabling addition, deletion or relocation of these sections to relocate the brake means section, the curved section and the supporting member without changing the configuration of the curved section and the supporting member to adjust for different trim widths of webs.
In a further embodiment in accord with the present invention, the track includes a plurality of spaced elongated air passages located below the upper portion of the track and a plurality of spaced passageways communicating fluidly between the air passages and the channel for receiving compressed air to inhibit entry into the channel of contaminants from the surrounding environment and to control the temperature of the channel.
In an alternative embodiment of the present invention, the track includes coolant passages located below the upper portion of the track for receiving coolant at a lower temperature than the channel to control the temperature of the channel.
An alternative embodiment of the present invention has a single flap means fastened to one side of the upper portion and substantially extending over the channel to frictionally engage the tape when it exits transversely from the channel.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1
shows a prior art apparatus
10
used in the paper industry to cut a moving web of paper
29
being wound up on a spool
28
and to transfer the cut edge of the paper to an empty wind up spool
24
without having to stop the paper movement. In order to cut the moving paper web
29
and start it winding onto the empty spool
24
, a cutting tape
11
, not shown, is moved forward and is caught in the nip
22
formed between the web driving spool
26
and the empty spool
24
. The tape
11
is wrapped helically around the spool
28
and in so doing it cuts through the paper web
29
and leads the cut edge onto the empty spool
24
, which continues to wind up the web
29
until it is full and the entire operation is repeated to cut and transfer the web to a new, empty wind up spool. Soon after, the web
29
is transferred to the spool
24
, the spool
28
is moved away from the drive spool
26
and a new empty spool is moved down to the previous position of the full spool
28
.
The tape
11
, which is introduced into the track
14
is directed to a dispensing section, not shown, where it is treated to apply a coating pressure sensitive adhesive to the forward portion of the tape
11
. The tape
11
is then cut into a finite length and pushed along until the tape
11
is at the end of the curved section
16
. The tape
11
is then stopped and held in position until an operator decides it is time to cut and transfer the web
29
to a new spool. In order to cut the web
29
properly, it is crucial that the cutting tape
11
be tensioned enough to cut the paper web
29
and not merely pulled. However, the prior art generally, except Applicant's U.S. Pat. No. 6,305,634, lacks any means to control the tension in the cutting tape after exiting from the brake section
12
and until attaching to the nip
22
formed between a web driving spool
26
and an empty spool
24
.
Another problem with the prior art results from contact of the tensioned tape
11
with the channel
15
in which the tape
11
passes through. A further problem with the prior art is the need to adjust the entire track assembly
10
including the position of the brake section
12
and the configuration of the curved section
16
for every different trim width for various paper webs used in the paper making industry. The present invention discloses an improved track assembly designed to overcome these and other problems with the prior art.
FIG. 2
shows the track assembly
30
of the present invention and includes a track
34
, which is generally an H-shaped structure and has an upper portion
37
wherein a channel
50
is formed that functions as a guideway for the cutting tape
52
. The track
34
has a lower portion
38
that rests on a track carrier
36
. The upper portion
56
of the carrier
36
is generally of a concave shape and abuts the lower portion
38
of the track
34
. The track
34
and the carrier
36
are secured together via spaced fasteners in the form of self-threading screws, or bolts and nuts, or the like that pass through the track
34
and the upper portion of the track carrier
36
. The track carrier
36
has a hollow inside
55
that has a complimentary shape to the upper portion
56
and lower portion
57
of an elongated fixed support or generally an I-beam shaped support
58
. The track carrier
36
has two supporting legs
35
A and
35
B and respective two lower portions
39
A and
39
B that extend beneath the lower portion
57
of the fixed support
58
. The track carrier
36
is fastened to the elongated fixed support
58
by an air craft pin
96
, which is a pull pin. In order to slide the carrier
36
, which carries the track
34
, along the elongated fixed support
58
, the pin
96
has to be pulled out to disengage the carrier
36
from the fixed support
58
.
The track assembly
30
of the present invention further includes a plurality of flap means, a first flap means
40
, a second flap means
42
and a third flap means
44
. The first flap means
40
is secured to one side of the channel
50
, which is formed in the upper portion
37
of the track
34
, by a fastener or a clamp
46
. The first flap means
40
extends over a portion of the cutting tape
52
less than a substantial portion to avoid frictional contact between the first flap means
40
and the second flap means
42
. The second flap means
42
is positioned directly opposite from the first flap means
40
and secured to another side of the upper portion
37
of the track
34
by a fastener or a clamp
48
. The first and second flap means,
40
and
42
, frictionally engage the cutting tape
52
to assist in controlling the movement of tape
52
and to tension the tape
52
enough to cut a paper web properly. The third flap means
44
forms a complete seal with the first and second flap means
40
and
42
to keep clean the adhesive placed on the tape
52
free from contaminants and debris from the surrounding industrial environment and to prevent build up of debris inside the channel
50
. The first flap means
40
and the second flap means
42
are preferably more pliable than the third flap means
44
to enable two different controlled resistances for controlling the exiting of the cutting tape
52
from the channel
50
and to provide for stiffer surface resistance as the tape
52
exits the channel
50
.
FIG. 3
shows a further embodiment in accord with the present invention that includes a plurality of elongated air passages means
64
extending throughout the entire track
35
and positioned below the upper portion
41
of the track
35
for receiving compressed air from an air source, not shown, to distribute air through the passageways
66
to inhibit entry into the channel
51
of contaminants from the surrounding environment. Cold air can be supplied throughout air passageways
66
to help keep the tape
53
afloat and minimize contact between the tape
53
and the channel
51
and thereby control the temperature of the channel
51
due to the frictional contact with the tape
53
.
FIG. 4
shows an alternative embodiment in accord with the present invention that includes a plurality of coolant passages
68
extending through the entire track
102
and receiving a coolant from a cold source, not shown, and positioned beneath the upper portion
103
of the track
102
to control the temperature of the channel
98
, which is frictionally heated by the tape
63
passing therethrough.
An alternative embodiment of the present invention is shown in FIG.
5
and includes a single flap means
105
fastened to one side of the track
108
by a fastener or a clamp
107
. The flap means
105
extends substantially over the channel
104
frictionally engaging the tape
106
to assist in tensioning the tape
106
and controlling its movement when it exits laterally from the channel
104
. The flap means
105
forms a complete seal to help protect the adhesive placed on the forward end of the tape
106
by an adhesive station, not shown, as illustrated in Applicant's numerous above-identified U.S. patents, from contaminants in the surrounding paper making industry environment and to prevent a build up of debris, from the surroundings, inside the channel
104
.
FIG. 6
shows a track
120
provided with a plurality of elongated spaced air passages
109
extending through the entire track
120
. The track
120
includes air passages to distribute air into the channel
122
beneath the tape
124
to control the temperature of the tape
124
and keep it clean from contaminants.
FIG. 7
shows another embodiment of the present invention that includes a plurality of coolant passages
128
extending through the entire track
130
to control the temperature of the tape
132
.
FIG. 8
shows a curved section
60
, which includes a first flap means
113
A and a second flap means
113
B positioned directly opposite from each other and that extend substantially over a guideway
112
through which the tape
140
passes. The flap means
113
A and B frictionally engage the tape
140
to assist in controlling its tension and speed when the tape
140
exits the curved section
60
to pass into the nip formed between an empty spool and a web driving spool and attaches to the empty spool by way of adhesive applied to the forward end of the cutting tape, as Applicant disclosed in his above-identified U.S. patents. The flap means
113
A and B extend laterally toward each other to cover the guideway
112
and seal against contaminants. The flaps
113
A and B are secured to the track
142
by a fastener or a clamp
110
. A plurality of elongated air passages
114
and passageways
116
extend through the entire track
142
to keep the guideway
112
clean from any contaminants that may affect the adhesive disposed on the tape
140
to attach to the empty spool or cause a build up in the guideway
112
that may interfere with the movement of the tape
140
. Alternatively, a coolant can be pumped into the passages
114
, without the need to use the passageways
116
, to cool the guideway
112
and the tape
140
. It may be desirable for a light web using a thin cutting tape to make other portions of the track beneath the web of the configuration shown in
FIGS. 8 and 8A
.
FIG. 8A
shows another embodiment of the curved section
60
in accord with the present invention having a pair of flaps
150
and
151
secured to the track
155
by a pair of fasteners or clamps
157
. The pair of the flaps
150
and
151
are designed to control the exit direction shown by arrow
160
of the cutting tape
152
from the guideway
153
. The flap
150
is made more pliable and longer than the other flap
151
in order to force the cutting tape
152
to laterally exit adjacent the more pliable and longer flap
150
.
A side view of a track assembly embodiment of the present invention is shown in FIG.
9
. The track
34
has a plurality of removable sections
32
located in proximity with the brake section
31
, located adjacent a tape dispensing system
90
that includes an adhesive station
92
and a supply spool
94
disposed beneath it, not part of the present invention. The track
34
terminates with a curved section
60
secured to a supporting member
62
, which are slidably movable on the elongated fixed support
58
carried by the structural support members
115
and
117
. In order to slide the curved section
60
and the supporting member
62
on the track
34
, a pin occupying hole
118
A, which is a pull pin, must be pulled out in order to slide the curved section
60
and the supporting member
62
along the track
34
to either position
118
B or C according to the desired trim width and thereafter insert the pin into either hole
118
B or C in order to secure them to the track
34
.
Each of the removable sections
32
is coupled to the track
34
via a removable air craft pin
96
, which is a pull pin. In order to disengage any of sections
32
from the track
34
, the pin
96
is pulled out and the desired section is simply lifted off the track
34
. This can readily be accomplished since the lower portions
39
A and
39
B of the track carrier
36
were machined off to enable separation of sections
32
and the brake section
31
from the elongated fixed support
58
.
The removability of section
32
enables changing the positions of the brake section
31
and the curved section
60
and its supporting member
62
to accommodate for different trim widths, a maximum trim designated as A, a variable trim width C and a minimum trim width B, without changing the configuration of these parts. For example, in order to move the brake section
31
from a maximum trim position A to a minimum trim position B, two sections
33
must be taken out and other movable sections must be relocated so that brake section
31
occupies its proper position relative to the minimum trim width B, as shown in FIG.
10
. The curved section
60
and its supporting member
62
, are then moved by pulling out the pin from hole
118
A and sliding them on the elongated fixed support
58
to their new proper position relative to the minimum trim width B without changing their configurations, as shown in
FIG. 10
, and then securing them to the track
34
by inserting the pin in hole
118
B.
Likewise, the brake section
31
and the curved section
60
and its supporting member
62
can be relocated to any of the desired trim widths without changing their configurations.
While the invention has been described with respect to certain specific embodiments, it will be appreciated that many modifications and changes may be made by those skilled in the art without departing from the spirit of the invention. It is intended, therefore, by the appended claims to cover all such modifications and changes as they fall within the true spirit and scope of the invention.
