Work-sensing Means To Control Work-moving Or Work-stopping Means Patents (Class 83/209)
  • Patent number: 4697485
    Abstract: A die cutting press for processing web material has a registration system which is operable to provide precise alignment of a shiftable die cutting unit along two axes during the time that the web material is advanced along a third axis toward the die unit, so that as soon as a defined area of the web reaches the die unit, the press can be immediately actuated to subject the web to the die cutting operation. In preferred forms of the invention, an indicator strip is printed on the length of the web and is detected by two spaced photo optical sensors movable with the die unit. A first control means, coupled to the sensors, selectively actuates in stepwise fashion either of two servomotors as may be necessary to bring the die unit into registration with defined web areas in a direction laterally of the web length (which may be defined as a Y axis) as well as a rotative orientation with respect to the defined web areas about an upright axis (which may be termed the .theta. axis).

  • Patent number: 4655067
    Abstract: A method and apparatus for cutting predetermined lengths of panels from a continuous strip of flexible material and for forming the lengths of panel members to have a preselected panel profile. The strip is reel fed to a first strip driving station which drives the strip through a shearing station, over a hump table, to a second strip driving station and through a strip forming station. In sequence, the second strip driving station brakes the leading portion of the strip to effect a strip hump over the hump table, which is detected by a protoelectric sensor for hump height and signals the first strip driving station to vary its feed rate to maintain the hump; the second driving station is then signaled to commence driving the lead portion of the strip to the strip forming station.

  • Patent number: 4594925
    Abstract: For severing a continuous slide fastener chain into individual slide fastener lengths, the chain having succesive coupling element portions and element-free gap sections on a stringer tape, a cutting station is preceded by a detecting unit. The detecting utilizes at least two sensors for sensing the leading end of each successive coupling element portion of the chain which is being conducted to the cutting station. The sensors are longitudinally spaced along the chain's path to the cutting station and produce respective command signals one after the other to a chain drive to reduce the moving rate of the chain in step fashion to a low speed as the gap section approaches the cutting station. This enables uniform and adequate quality fastener length cutting to be reliably achieved.

  • Patent number: 4569467
    Abstract: A lazy-susan type roll table supports, in a vertical position, a roll of place mats interconnected into a continuous web (i.e. each mat is attached to its adjacent mat by perforations and all are rolled up on a core to form the roll of material). A web feed roller, also disposed for rotation about a vertical axis, is spaced from the roll table and cooperates with a pinch roller to grip therebetween the web of place mats and to feed the place mats along a path. An end panel positioning plate receives the end place mat, as the web is being fed, and carries an infra-red sensor which responds to the presence of the perforations between the mats to terminate drive of the web feed roller. A web tension drive extends up through the core of the roll of place mats and mounts a soft rubber drive wheel which when driven urges the web roll in a direction opposite to that imparted to the web by the web feed roller.

  • Patent number: 4555968
    Abstract: A die cutting press for processing web material is disclosed which is operable to provide very precise alignment of a reciprocable die cutting unit with each succesive area of the web to be die cut. In operation, the web is incrementally advanced toward the work station of the press until the area next to be die cut is substantially but not exactly in the die cut position thereof. The web feed is then placed in a creep mode to advance the web until an optical sensor determines the presence of transverse alignment indicium on one side of the web. Mechanism is thereupon actuated to rotate the die unit as required to bring the die assembly into alignment with related indicium on the opposite side of the web while effecting shifting of the web longitudinally thereof in a direction of travel as necessary to maintain die registration with the first sensed web indicium.

    Abstract: A method and apparatus for automatically severing individual towels from a length of material comprising a plurality of terry towels. The method includes the steps of measuring slightly less than the supposed length of a towel, then activating a sensor that detects the edge of a cutting space by the change in thickness of the material. The sensor causes feeding of the material to stop with a cut-line at a cutting blade. The first edge of the material is held while a second sensor located the same edge at the opposite side of the material, and the cutting blade is moved with the sensor. The material is stretched to straighten the cut-line, and the cutting blade is caused to cut the material. The apparatus includes feed rolls to move the material, and an encoder measures the length. A roller at one edge of the material detects the change in thickness at one edge, and similar rollers detect the change in thickness at the opposite edge.
