Abstract
A method and apparatus for cleaning debris, such as lint-like residue, from the bristle blocks of an automatic fabric cutting machine cutting bed, utilizing a linear motion device connected to a head by motion-amplifying linkages in order to amplify the acceleration produced by the motion device and thereby accelerate a slat of bristle blocks toward a grate. When the slat contacts the grate it is abruptly decelerated, which causes the debris to travel out from between the bristles. The grate is indexed between cycles of the head so that different portions of the slat strike the grate each cycle.
Claims29
An apparatus for removing debris from a substrate comprising:
- a head;
- support means for supporting said substrate by said head;
- mover means for accelerating said head in a given direction, said mover means including means for producing linear movement and linkage means connecting said mover means with said head in a manner that said head is moved a greater amount than said mover means for amplifying said linear movement when applied to said head;
- and
- means for decelerating said head after said mover means has accelerated said head;
- wherein said linkage means includes an elongated member having first and second opposite ends, said linear movement being applied to one of said opposite ends, the other one of said opposite ends being connected to said head, said linkage means further including means for pivotally mounting said elongated member at a pivot point between said first and second opposite ends, wherein the distance between said pivot point and said one of said opposite ends being less than the distance between said pivot point and said other one of said opposite ends.

An apparatus for removing debris from a substrate comprising:
- a frame;
- a head assembly vertically reciprocal with respect to said frame, said head assembly including means for mounting a substrate thereto;
- an extendable force producing device connected with said frame;
- linkage means connected with said force producing device and said head assembly for transmitting force from said force producing device to said head assembly to reciprocally move said head assembly along a path, said linkage means including an elongated member pivotally mounted at a pivot point to said frame, first connecting means for connecting a first portion of said elongated member to said force producing device and second connecting means for connecting a second portion of said elongated member to said head, the distance between said pivot and said first connecting means being less than the distance between said pivot and said second connecting means;
- and
- an abutment positioned in said path for contacting said substrate and thereby dislodge debris therefrom.

An apparatus for removing debris from a substrate comprising:
- mover means for inducing reciprocal movement in a substrate toward and away from a given location;
- a grate having a plurality of lattice members, said grate being positioned at said given location such that a substrate will contact said lattice members when reciprocated toward said given location;
- and
- indexing means for laterally indexing the positional relationship between said grate and said mover means such that different portions of a substrate will contact said lattice members.

An apparatus for removing debris from a bristle member comprising:
- a head extending in a plane;
- support means for fixedly supporting a bristle member to said head in said plane whereby any motion imparted to said head is imparted to said bristle member;
- mover means for reciprocally moving said head perpendicular to said plane from a first position to a second position during a first portion of a cycle and from said second position to said first position during a second portion of said cycle;
- and
- said mover means selectably controlling the velocity of said head at all times during both said first and second cycle portion in a manner that said head achieves a substantially greater velocity during said first portion than during said second portion such that debris dislodged during said first portion will not be relodged during said second portion and cycle speed can be maximized to enhance debris dislodging;
- and
- a generally planar grate positioned at said second position oriented generally parallel said plane in order to interrupt the movement of said head to abruptly decelerate said head at said second position.
