DETAILED DESCRIPTION
[0006] Fig. 1 shows a trimmer 10 according to an embodiment of the present invention. Trimmer
10 includes an infeed 12, a decelerator 14 downstream of infeed 12 and a trimming
station 18 downstream of decelerator 14. In this embodiment, trimming station 18 trims
a front or face of sheet material articles (i.e., an edge opposite the spine) and
trimmer 10 includes a side trimming station downstream of trimming station 18. Sheet
material articles are sequentially fed from infeed 12 at a constant infeed speed to
decelerator 14. At infeed 12, sheet material articles are registered with infeed register
belts 20, 22 at register pins 24, 26 and passed to forwarding belts 28, 30. Infeed
register belts 20, 22 and forwarding belts 28, 30 run at the same infeed speed. The
sheet material articles leave infeed 12 at the outlet of forwarding belts 28, 30 and
are received by decelerator 14 at a deceleration nip 32, which in this embodiment
is formed by a lower decelerator section 34 of fixed position lower deceleration rollers
36, 38 and an upper decelerator section 40 of actuating upper deceleration belts 42,
44. In a closed position of deceleration nip 32, upper deceleration section 40 contacts
an upper side of the sheet material article and lower deceleration section 34 contacts
a lower side of the sheet material article. In an open position of deceleration nip
32, upper deceleration section 40 is spaced away from the sheet material article and
does not contact the upper side of the sheet material article.
[0007] As deceleration nip 32 receives the sheet material article from infeed 12, a trailing
edge of the sheet material article is still in contact with forwarding belts 28, 30
and a surface speed of the deceleration nip 32 is equal to the infeed speed (i.e.,
the surface speed of belts 20, 22, 28, 30). After the sheet material exits infeed
12, i.e., after a trailing edge of the sheet material article is no longer in contact
with forwarding belts 28, 30, the surface speed of deceleration nip 32 is decreased,
decelerating the sheet material article using deceleration nip 32. As sheet material
enters into trimming station 18, i.e., when a leading edge of the sheet material articles
contacts a trimming station transporter 46, which is formed by an upper transport
conveyor 48 for contacting the upper side of the sheet material article and a lower
transport conveyor 50 for contacting the lower side of the sheet material article,
the surface speed of deceleration nip 32 is equal to a surface speed of trimming station
transporter 46. Deceleration nip 32 and trimming station transporter 46 then decelerate
the sheet material article together until the sheet material article exits deceleration
nip 32, i.e., when a trailing edge of the sheet material articles is no longer in
contact with lower decelerator section 34 and upper decelerator section 40.
[0008] After the sheet material article exits deceleration nip 32, trimming station transporter
46 continues to decelerate the sheet material article until the sheet material article
comes to a complete stop. Once the sheet material article is stopped, a trimming device
52 trims an edge of the sheet material article. In this embodiment, decelerator 14
and trimming station transporter 46 are driven by a common drive, such that the surface
speed of trimming station transport 46 is always equal to the surface speed of deceleration
nip 32. In order to avoid problems for a following sheet material article entering
deceleration nip 32 while the surface speed of deceleration nip 32 is lower than the
infeed speed (i.e., the surface speed of the following sheet material article), deceleration
nip 32 is opened after the sheet material article exits deceleration nip 32 (as shown
with respect to book 58 in Fig. 4a). Accordingly, while lower decelerator section
34, upper decelerator section 40, upper transport conveyor 48 and lower transport
conveyor 50 are driven to have a lower surface speed than the infeed speed and a following
sheet material article has entered into deceleration nip 32, upper decelerator section
40 is actuated to be spaced away from lower decelerator section 34 such that upper
decelerator section 40 does not contact the upper side of the following sheet material
article and nip 32 is in the open position. Once the sheet material article is trimmed
by trimming device 52, lower decelerator section 34, upper decelerator section 40,
upper transport conveyor 48 and lower transport conveyor 50 are accelerated such that
conveyors 48, 50 accelerate the trimmed sheet material article away from trimming
device 52 and sections 34, 40 are accelerated to have a surface speed is again equal
to the infeed speed. After the surface speed of deceleration nip 32 reaches the infeed
speed, deceleration nip 32 is closed to grip the subsequent sheet material article,
by actuating upper decelerator section 40 back toward lower decelerator section 34.
[0009] Fig. 1 shows three sheet material articles 54, 56, 58, which are for example books
traveling in a direction 60, at their relative positions when infeed 12 and trimming
station transporter 46 (along with decelerator 14) are running at matched speed. First
book 54 is shown at infeed register belts 20, 22 with a leading edge spine 54a of
book 54 against register pins 24, 26. Second book 56 is shown with its trailing edge
56b in a nip 70 formed by upper forwarding belt 28 and lower forwarding belt 30. Leading
edge 56a of book 56 is shown in deceleration nip 32 being gripped and transported
by decelerator sections 34, 40. Third book 58 has already been trimmed by trimming
device 52 and is shown between upper trimmer transport belts 62, 64 of upper transport
conveyor 48 and lower trimmer transport belts 66, 68 of lower transport conveyor 50
being transported at the infeed speed. A lower knife 72 of trimming device 52, which
made a face cut 74 at trailing edge 58b of book 58, is shown at the entrance to trimming
station 18, just ahead of trimmer transport belts 62, 64, 66, 68.
[0010] Figs. 2a and 2b illustrate the transfer of book 56 from register belts 20, 22 to
forwarding belts 28, 30. In Fig. 2a, pins 24, 26 register leading edge 56a, which
in this embodiment is the spine, prior to entering forward belt nip 70. Forwarding
belts 28, 30 run at the same speed as pins 24, 26. Once book 56 is under control of
forwarding belts 28, 30, pins 24, 26 rotate away from leading edge 56a and travel
in a return path 76. (similar to register and control disclosed in Fig. 4 of
U.S. Patent 8,186,252).
[0011] Figs. 3a and 3b are cross-sectional views of Fig. 1. Instead of transporting books
54, 56, 58 as in Fig. 3a, trimmer 10 is transporting books 78, 80, 82, which are larger
than books 54, 56, 58, in Fig. 3b. Books 78, 80, 82 are a little more than twice the
length of books 54, 56, 58. Additionally, an upper knife 84 of trimming device 52,
which was omitted from Fig. 1 for clarity, is in its raised position above lower knife
72. Both Figs. 3a and 3b show books at similar points in the transport cycle, when
infeed 12 and trimming station transporter 46 (and thus also decelerator 14) are running
at matched speed (zone A of Fig. 5). In this embodiment, trailing edge 56b of book
56 in Fig. 3a and trailing edge 80b of book 80 in Fig. 3b will be in the same position
relative to front knives 72, 84 at any point in the cycle, regardless of the book
length. As shown in Figs. 3a and 3b, longer books may be gripped by all of forwarding
belts 28, 30, decelerator section 34, 40 and conveyors 48, 50 at the same time, while
shorter books exit forwarding belts 28, 30 before being gripped by conveyors 48, 50.
Similarly, in this embodiment, cut edge 58b of book 58 in Fig. 3a and cut edge 82b
of book 82 in Fig. 3b will be at the same position (zone D of Fig. 5) relative to
front knives 72, 84 at any point in the cycle, as well.
[0012] Figs. 4a and 4b are cross section views similar to Figs. 3a and 3b, but show books
54, 56, 58 and books 78, 80, 82, respectively, at an earlier point in the transport
cycle. The face cut on trailing edges 58b, 82b have just been completed and books
58, 82 have started to move away from knives 72, 84 (zone D of Fig. 5). Upper knife
84 is starting to rise and transport conveyors 48, 50 have started to accelerate books
58, 82 from stationary state (zero speed), which existed when the front cut was made
by trimming device 52. Books 54, 56 in Fig. 4a and books 78, 80 in Fig. 4b are traveling
at a constant infeed speed (zone A of Fig. 5). Because fixed position lower deceleration
rollers 36, 38 and actuating deceleration upper belts 42, 44 are running at the transport
speed of trimming station 18, deceleration nip 32 is opened by raising belts 42, 44
to allow book 80, which is traveling at a faster speed than a surface speed of belts
42, 44, to pass through nip 32.
[0013] Fig. 5 shows a graph illustrating the speed E of a book during one cycle. In a zone
A, the book is in forwarding belts 28, 30 and travels at an infeed speed F. Deceleration
nip 32 begins gripping the book in zone A, when a surface speed of nip 32 matches
the infeed speed F. In a zone B, the book is in deceleration nip 32 initially and
is transferred at match speed to trimmer transport belts 62, 64, 66, 68 while being
decelerated to zero speed. The book is released by deceleration nip 32 in zone B before
the book reaches zero speed. In a zone C, the book is stopped and trimming by trimming
device 52 occurs. In a zone D, the book is still captured by trimmer transport belts
62, 64, 66, 68 and accelerated back to infeed speed F. When the book is in forwarding
belts 28, 30, its speed matches the infeed speed F, which is constant. After the book
exits the forwarding belts 28, 30, it is decelerated to zero speed in zone B. When
at zero speed in zone C, a trailing edge of the book is cut by trimming device 52.
When the cut is completed the book is accelerated D back up to the infeed speed F.
[0014] Fig. 6 shows drive components 86 of lower deceleration rollers 36, 38 and upper deceleration
belts 42, 44. Also shown is a cam arrangement 88, which together with actuator 92
(Figs. 7 and 8) actuates upper deceleration belts 42, 44. Deceleration rollers 36,
38 and belts 42, 44 are driven by a common belt 90. This drive is connected to the
same motor that drives the trimmer transport belts 62, 64, 66, 68, resulting in a
speed match between trimmer transport belts 62, 64, 66, 68 and deceleration rollers
36, 38 and belts 42, 44. Upper decelerator section actuators 92, 94 and lower deceleration
rollers 36, 38 are connected by mounting structures 96, 98. Drive shafts 100, 102
are splined so that upper decelerator section actuators 92, 94 and lower deceleration
rollers 36, 38 can be moved in and out to accommodate different book widths. Upper
drive shaft 102 passes through the upper belt pivot. This allows upper belts 42, 44
to rotate around the centerline of upper drive shaft 102 to open and close deceleration
nip 32.
[0015] A cam 104 is driven by a chain 106 connected to the mechanism that also raises and
lowers upper knife 84. Cam 104 rotates once per cycle just as upper knife 84 moves
up and down once per cycle to cut each book. A cam follower bearing 108 rotates on
cam 98 and is mounted to a lever 110, pivoting on a stud 112. Lever 110 is loaded
against cam 104 by a spring 114. A connecting rod 116 connects cam lever 110 to a
drive lever 118 mounted on the end of a belt actuating shaft 120. Belt actuating shaft
120 is also splined to allow adjustment of upper decelerator section actuators 92,
94 for different book width.
[0016] Fig. 7 shows a cross-section view of upper decelerator section actuator 92 and Fig.
8 shows a detailed view of upper decelerator section actuator 92 in an open position.
Upper deceleration section actuator 92 moves upper decelerator section 40 away from
lower decelerator section 34 to open and close nip 32. Belt actuating shaft 120 pivots
a splined sleeve 122 mounted in a housing 124. Connected to sleeve 122 is a lift lever
126. Lift lever 126 is connected to a deceleration belt lever 128 with a compression
spring 130 and spring cups 132, 134. Deceleration belt lever 128 is mounted to a sleeve
136 which also pivots in housing 124. The arrangement of the levers 126, 128 results
in a four bar mechanism. Spring 130 is a flexible connection between levers 126, 128,
allowing deceleration nip 32 to self adjust for varying book thickness.
[0017] A timing belt pulley 138 is mounted on a splined bore sleeve 140 that is connected
to deceleration belt lever 128 and sleeve 136 by a bearing 142 which allows deceleration
belt lever 128 to pivot up and down while timing belt pulley 138 spins upper deceleration
belt 42. Splined bore sleeve 140 is driven by splined upper drive shaft 102. Upper
deceleration belt 42 wraps an idler pulley 144 mounted on bearings 146 to the end
of deceleration belt lever 128. Upper deceleration belt 42 is positioned directly
above lower deceleration roller 36 and deceleration nip 32 is created between belt
42 and roller 36 as deceleration belt lever 128 and belt 42 pivot downward.
[0018] Fig. 9 shows a deceleration nip 148 in accordance with another embodiment of the
present invention. In contrast to deceleration nip 32, where upper deceleration belts
42, 44 form deceleration nip 32 with lower deceleration rollers 36, 38, deceleration
nip 148 is formed by lower deceleration rollers 36, 38 and upper deceleration rollers
150, 151, which are mounted adjacent to respective upper deceleration belts 42, 44
and are driven by respective upper deceleration belts 42, 44.
[0019] Fig. 10 shows a deceleration nip 152 in accordance with another embodiment of the
present invention. In contrast to deceleration nip 32, upper deceleration belts 42,
44 have been replaced by undriven idler rolls 154, 155, mounted to and actuated by
levers 156, 157. Lever 156 is actuated by upper decelerator section actuators 92,
94 forming the previously described four bar mechanism. In another embodiment, upper
decelerator section actuators 92, 94 may be eliminated and lever 156 may be actuated
directly with an actuating shaft passing through a pivot center 158.
[0020] Fig. 11 shows a deceleration nip 160 in accordance with another embodiment of the
present invention. In this embodiment, width-adjustable lower deceleration rolls 36,
38 have been replaced by a driven full width roll assembly 162.
[0021] Fig. 12 shows a deceleration nip 164 in accordance with another embodiment of the
present invention. In this embodiment, upper deceleration belts 42, 44 have been replaced
by a driven full width roll assembly 166, which forms deceleration nip 164 with driven
full width roll assembly 162. Full width roll assembly 166 is driven by gears 168,
connected to a belt 170 and is actuated by a cam mechanism 172.
[0022] Fig. 13 shows a deceleration nip 174 in accordance with another embodiment of the
present invention. In this embodiment, upper deceleration belts 42, 44 have been replaced
by axially-adjustable upper wheels 176, 177 which forms deceleration nip 174 with
driven full width roll assembly 162.
[0023] Figs. 14a and 14b show a decelerator 178 according to another embodiment of the present
invention. In this embodiment, a non-reciprocating segmented wheel 178 is provided
for opening and closing a deceleration nip 180 formed by wheel 178 and a roller 182.
Wheel 178 includes an outer circumferential surface of two different radial heights.
A larger circumferential surface 184 having a greater radial height decreases the
size of nip 180 and contacts a book 188 and a smaller circumferential surface 186
having a lesser radial height than larger circumferential surface 184 opens up nip
180 such that wheel 178 does not contact book 188 when the surface speed of wheel
178 (and the surface speed of trimmer station transporter 46) is less than the infeed
speed. Wheel 178 and roller 182 may be connected to the same drive as trimmer station
transport 46 so that the surface speed of larger circumferential surface 184 is equal
to the surface speed of trimmer station transporter 46. Fig. 14a shows a book 188
traveling at infeed speed while wheel 178 has a surface speed less than the infeed
speed. In Fig. 14b, book 188 has been transferred at matched speed from forwarding
belts 28, 30 to wheel 178 and a roller 182 and deceleration nip 180 begins to decelerate
book 188.
