  • FIGS. 7 to 11 are schematic graphs of the pulses occurring in the circuit of FIG. 6, the ordinates representing voltages and the abscissae representing time.
  • the cutting apparatus of the present invention includes a frame 1 mounted on a base plate 3.
  • the frame 1 is connected tothe base plate 3 by bolts 4 and 5, which permit vertical adjustment of the frame 1 on the base plate 3.
  • the upper end 6 of the frame 1 is in the form of a yoke 7 or split ring for slidably supporting an arm 8, which extends ou'twardly fromthe yoke 7 over a flat tablev portion 10 of the frame 1.
  • a pair of bolts 11 interconnect opposing ends 13 of the yoke 7 for securing the arm 8 in any desired position.
  • the object of the present invention is to solve the i above problem by providing a'cutting apparatus for relatively rapidly and accurately cutting a binding tape between a plurality of components fed from a sewing machine.
  • the present invention relates-to a cut- 7 ting apparatus for cutting astrip of material connected to a component andfextending beyond at least one edge thereof, the cutting being performed at said edge, such apparatus including an electromagnetically operated plunger with ablade on the outer end thereof.
  • a sensing device is provided for detecting the location of the edge of the'component, and transmitting a signalto the drive portion of the electromagnetic apparatus, whereby the plunger is actuated to cut the tape at such edge.
  • a generally cylindrical casing 15 is securely mounted onthe outer end of the arm 8 and forms part of a cutting. device.
  • the casing 15 includes integral top and side walls 16 and 17, respectively, an abottom wall 19.
  • the bottom wall 19 is provided with inwardly and outwardly extending tubular portions 20 and 21, respectively which form a housing for a plunger 23 in the form of a rod.
  • the inner end 25 of the tubular wall portion 20 is provided.
  • the plunger 23 is bevelled, i.e., frusto-conical in cross-sectional configuration for mating with a frusto-conical recess 26 in the bottom endof a cap 28 provided on the .upper end of the plunger 23 in the casing 15.
  • the inwardly extending tubular wall portion 20 and the cap 28 are sur- 1 rounded in the casing 15 by a coil 30 forming part of an electromagnetic circuit (described hereinafter in greater detail).
  • thecap 28- on the plunger23 forms amagnetic core for the electromagnetic circuit
  • the cap 28 is normally biased upwardly .away from the bottom wall 19 of the casing 15 by a helical spring 32 mounted coaxially on the plunger 23, and
  • a flat, generally rectangular blade 35 is'securely mounted in the recessed lower
  • the blade 35 is self-adjusting, i.e., when the' flat cutting edge 45 strikes a flat surface, the blade 35 can rotate about the axis of the bolt 38 so that the entire cutting edge 45 strikes such flat surface.
  • a hard metal insert 46 is provided in the table portion 10 of the frame 1.
  • a V-shaped notch 48 in the insert 46 facilitates proper cutting action, since the vertex of the notch 48 defines the point of cutting;
  • the insert 46 is located in an anvil '50, which is removably mounted on the table portion 10, whereby the anvil 50 and insert 46 can readily be replaced when damaged or otherwise altered by wear.
  • the holder in the form of a plate 52 is removably mounted with bolts'54'at the side of the table portion 10 adjacent to the anvil 50 for photoelectric sensors 56 and 57.
  • the sensors 56 and 57 include a pair of photoelectric cells 58 and 59 mounted at spaced apart points in the plate 52, and fibreglass filaments (not shown) extending upwardly to adjacent the top surface of the plate 54 fortransmitting light from a light source 60 to the photoelectric cells.
  • the useof fibre optics in the sensors 56 and 57 renders the sensors much more sensitive to the presence or absence of light from the light source 60.
  • a binding tape 63 (FIG. 5) is being continuously sewn onto an upper component-65 travelling in the direction of arrow 66 through'a sewing machine 68, it is desirable to cut the binding strip at the leading edge 69 and at the trailing edge (not shown) of the-component 65. Since the components 65 are fed very quickly through the sewing machine 68, the time lapse between cuts (particularly between cuts at the trailing edge of one component and the leading edge of the next component) is very small.
  • the sensors 56 and 57 form parts of a circuit (FIG. 6) including pulse conditioners 71 and 72 for modifying the output signal 74 (FIG. 7) from the sensor 56 to form pulse 75 (FIG. 8).
  • the pulse 75 is fed into a gating pulse timer 76, in which the pulse 75 is modified to pulse 78 (FIG. 9).
  • the pulse 78 opens gates of pulse conditioners 80 and 81, the former of which also receives a pulse 74' (FIG. 7) from the sensor 57. If during the existence of pulse 78, a change of illumination of sensor 57 occurs, pulses 83 and 84 (FIG. are emitted by the pulse conditioners 80 and 81.
  • Thepulses 83 and 84 are modified by trigger pulse systems 86 and 87 to form trigger pulses 89 and 90.
  • the trigger pulses 89 and 90 control power impulse systems 92 and 93, which discharge condensers 95 and 96 into the coil 30 in the casing 15.
  • thecondenser 95 is discharged into thecoil 30 when the sensor 57 is illuminated and condenser 96 is discharged. when the sensor 57 is occluded or blanked, but only when gating pulse 78 is available.
  • the binding tape 63 is continuously sewn onto an upper component 65, and the resulting product is fed to the. cutting apparatus, i.e., onto theanvil 50.
  • the sensors 56 and '57 are occluded by the component 65, and, upon occlusion of the second sensor 57, the condenser 95 discharges to energize'the coil 30 which causes the cap 28 (i.e.-, core) to movedownwardly' with the plunger 23 and the blade 35 to cut-the tape 63 at the leading edge 69 of the component 65.
  • the helical spring 32 immediately returns the cap 28, the plunger 23 and the blade 35 to the rest position (FIG.
  • the time of chopping and the energy of impact of the blade are dependent on (1) the parameters of the solenoid defined by the cap 28, coil 30 and plunger 23, (2) the mass of magnet core defined by cap28 and the plunger 23, (3) the spring 32 and (4) the charge of condensers 95 and 96.
  • Such parameters should be designed so'that the binding tape or strip 63 is cut in time shorter than 3 milliseconds and within a tolerance of, for example, 1:1/32inch.
  • the cutting apparatus can be used for cutting any strip of material, e.g., thread or tape, connected to a component and extending beyond at least one edge thereof.
  • the component can be any textile or shoe component.
  • a cutting apparatus for cutting a strip of binding tape connected to a shoe upper component and extending beyond at least one edge thereof, the cutting being 7 performed at said one edge, said apparatus comprising a frame; a yoke on said frame; an arm slidably mounted in said yoke; a table portion on said frame for receiving said component and tape; a casing onone end of said arm opposite said yoke and above said table portion of the frame; plunger means housed in said casing and projecting therefrom toward said table portion of the frame; blade means on the outer end of said plunger for cutting said tape during passage of thecomponent and tape over said table portion of the frame; electromagnetic drive means for moving said plunger and blade means from arest position to a cutting position; sensor means for actuating said drive means when said component and said tape are properly located beneath said blade means; and means for returning said plunger I means and said blade means to said rest position, said electromagnetic drive means including a core formed of magnetic material mounted on said plunger means in said casing; a coil
