Abstract
Description
- This application is a continuation of U.S. patent application Ser. No. 10/437,577, filed on May 14, 2003, the entire disclosure of which is hereby incorporated by reference.
- The present invention relates to sheet material feeders, for example hoppers for feeding sheet material such as signatures, individual sheets or inserts from a pile.
- German Patent Application No. 197 38 920 for example discloses a feeder for taking a signature from a pile of signatures using a suction device, which passes the signature to a rotating drum. Grippers on further opening drums then open the signatures as the signatures are transported to a saddle-back conveyor.
- U.S. Pat. No. 6,213,457 discloses an apparatus for feeding flat products from a pile using a sucker and conveying belts. The flat products are then passed to a feeder conveyor, either directly or via a gripper drum running at a stable surface speed ten percent greater than the speed of the flat products.
- A problem with conventional feeders is that the separation process for the bottom sheet material is prone to difficulties at high speeds. For example, inertial forces and vacuum building for the suckers creates limits on the speed for the feeder.
- The present invention provides a sheet material feeder comprising: a sheet material holder for holding a pile of sheet material; a rotating drum for transporting the sheet material from the pile; and an acceleration device receiving the sheet material from the rotating drum at a first speed and releasing the sheet material at a second speed greater than the first speed.
- By providing an acceleration device in conjunction with the rotating drum, the drum can rotate at a slower speed to remove the sheet material from the pile, while the acceleration device provides for increased delivery of the sheet material. Thus for a particular feeder speed, removal of the sheet material can occur more effectively due to the lower rotating drum speed.
- The acceleration device preferably includes a plurality of variable-speed belts, and may further include two intake nip rollers and two output nip rollers over which the belts run. The surface speed of the output nip rollers is then greater than the surface speed of the input nip rollers.
- The rotating drum preferably includes a plurality of grippers, so that more than one sheet material is obtained from the stack per revolution of the drum.
- The grippers preferably include a first gripper part and a second gripper part, each gripper part being individually actuable.
- The holder may include an adjustable bottom tray, and a restrictor.
- A caliper and pressure roller may be provided to interact with the gripper drum prior to the acceleration device. The roller may be eccentrically mounted.
- Preferably, the drum further includes suckers. The suckers thus are no longer separate from the drum, and may be actuated by rotation of the drum.
- The present invention thus also provides a sheet material feeder comprising: a sheet material holder for holding a pile of sheet material; and a rotating drum for transporting the sheet material from the pile, the rotating drum including at least one sucker rotating with the drum for contacting the sheet material.
- By having the sucker rotate with the drum, complex reciprocating parts such as independent suck bars and lift feet may be eliminated.
- The present invention will be described with respect to a preferred embodiment in which:
-
FIG. 1 shows a side view of a preferred embodiment of the present invention; -
FIG. 2 shows a first step of sheet material removal from on the sucker/gripper pairs of the rotating drum; and -
FIGS. 3, 4 , 5, 6, 7, 8, 9, 10, 11, 12 and 13 shows steps subsequent to the step inFIG. 2 . -
FIG. 1 shows a side view of a preferred embodiment of the feeder of the present invention.Sheet material 10 is held in aholder 20, which has anadjustable bottom tray 22 and a bottom opening 24.Bottom tray 22 is adjustable to alter the size of the opening 24.Sheet material 10 may include signatures, which have a folded edge resting against afront wall 26. Anadjustable restrictor 28 may protrude from the front wall into bottom opening 24. - The feeder further includes a rotating
drum 30 having a plurality ofgrippers 32 andsuckers 34, which can be connected to cam followers and moved and actuated by cams adjustable forvarious sheet material 10 lengths. Eachgripper 32 has afirst gripper part 35 and asecond gripper part 36, which pivot about apivot point 38 and each of which may have its own cam. The twogripper parts grippers 32 andsuckers 34 may be spaced axially on thedrum 30, thegrippers 32 andsuckers 34 preferably alternating and being spaced axially apart. - The
suckers 34 can take suction from an adjustable vacuum pad ondrum 30, which may be connected to a vacuum source apart fromdrum 30. - Interacting with an outer surface of
drum 30 is an eccentrically-mounted rotatingpressure roller 40, located in front of anacceleration device 50.Acceleration device 50 includes two take-off belts drum 30, and thus spaced axially with respect togrippers 32 andsuckers 34 as well.Belts input rollers output rollers belts input rollers drum 30, which may rotate at a constant speed. The belts accelerate through thedevice 50, so that the surface speed of thebelts output rollers input rollers - FIGS. 2 to 13 show the gripping of a bottommost one of the
sheet material 10 for one set ofgrippers 32 andsuckers 34. -
FIG. 2 shows asucker 34 attached tosheet material 10, asdrum 30 rotates in direction D. Sucker 34pulls sheet material 10 downwardly, so that thevacuumed sheet material 10 passes therestrictor 28, as shown inFIG. 3 . - Sucker 34 then pulls
sheet material 10 to gripper 32, which then grips the front edge ofsheet material 10, as shown inFIGS. 4 and 5 . - Once the sheet material is gripped the vacuum to
sucker 34 is cut and gripper 32 moves counterclockwise to free thesheet material 10 fromsucker 34, as shown inFIGS. 6, 7 and 8. Sucker 34 retracts intodrum 30. -
Sheet material 10 is then pressed against the outer surface ofdrum 30 bypressure roller 40, whilegrippers 32 stillgrip sheet material 10, as shown inFIG. 9 .Pressure roller 40 may be made of a plurality of axially-spaced disks, thegrippers 32 passing between the axial spaced of the disks.Pressure roller 40 may be eccentric so that contact withdrum 30 is selective and space is provided forsheet material 10 assheet material 10approaches pressure roller 40, this space being shown schematically in FIGS. 4 to 8. -
FIG. 10 showssheet material 10 enteringacceleration device 50. Oncesheet material 10 entersbelts second gripper part 36 is rotated as shown inFIG. 11 so thatgripper 32 opens andsheet material 10 can passsecond gripper part 36 as sheet material accelerates throughacceleration device 50. -
FIG. 12 showssheet material 10 exitingacceleration device 50, andFIG. 13 showsgripper 32 returning to grip the another piece ofsheet material 10. - Since
many grippers 32, for example 4, 6 or 8, may be spaced circumferentially about thedrum 30, thedrum 30 can pull off a plurality of pieces ofsheet material 10 per revolution at a speed slow enough to ensure good transfer from theholder 20, whileacceleration device 50 ensures that feeder throughput is not degraded. - While the present invention has been described with respect to a preferred embodiment, a similar device could be used for example in a forced shingling device (where the drum would rotate in the opposite direction and shingle the sheet material 10). The feeder could be used in a saddle stitcher or for perfect binding.
