Definitions

  • a primary switch of a control circuit is closed to energize a motor and clutch to drive a carriage for relocating positive stops limiting travel of one or more thread guides and to energize a signalling device.
  • the carriage and thread-guide stops are precisely positioned automatically by interposition of a preset blocking member between the source of a light beam, magnetic field or air jet of the signalling device and its signal receiver to open a secondary switch in the control circuit and thereby affect instantaneous deenergization of the motor and clutch and actuation of an auxiliary lock to prevent overtravel of the carriage on its feed screw.
  • the clutch may be disengaged by a photoelectric counter responsive to the angle of rotation of the feed screw.
  • Several signalling devices and receivers may be mounted on the carriage and connected in parallel to open sequentially secondary switches in the control circuit, in which case the primary switch is a sequential or stepping selector switch.
  • One such device includes a carriage having a positive stop engageable by a microswitch carried by the thread guide.
  • the carriage is repositioned by a feed screw driven by a servomotor
  • the circuit to the motor is opened.
  • the switching mechanism is dependent on a mechanical switch actuation, the switching time cannot be precisely determined.
  • a ratch stop is provided in order to locate the carriage precisely.
  • a slip clutch has been interposed between the servomotor and the carriage in order to isolate the inertial force of the servomotor from the positively-stopped carriage.
  • a different known device permits automatic adjustment of the thread-guide stops in opposite directions. Shortly before the carriage reaches the final position a disk clutch is released by a microswitch closed by the carriage. Closing of the microswitch actuates a relay to engage a cam follower roll with a cam. Such cam actuates a ratchet to terminate movement of the carriage upon reaching its proper position and to deenergize the servomotor. Simultaneously with the stopping of the carriage an index bolt is engaged with a feed-screw lock to hold the carriage to its proper position. Such a device does not stop the carriage precisely because of the difficulty of adjusting the cam accurately for the amount of inertial rotation of the feed screw after the clutch has been released.
  • neither of the devices discussed above nor any other known device permits automatic presetting for programming of the thread-guide setting mechanism for knitting a series of unlike pieces in succession, such as the four pieces required for a pullover sweater, namely, the front, the back and two sleeves, nor can the four-piece cycle be repeated automatically.
  • Another important object is to provide such setting mechanism which can be preset to position the thread guide for the beginning of knitting of successive unlike garment components automatically in proper sequence.
  • FIG. 1 is a top perspective of the thread-guide-positioning and position-signalling mechanism.
  • FIG. 2 is a diagram of the control circuit for the mechanism shown in FIG. 1.
  • FIG. 3 is a diagrammatic section through an alternate'form of signalling mechanism and FIG. 4 is a diagrammatic plan of another form of signalling mechanism.
  • FIG. 5 is a top perspective of still a different type of signalling mechanism including a diagram of the control circuit actuated by such mechanism.
  • FIG 6 is an enlarged detail of a modified component of the signalling device shown in FIG. 1. 7
  • FIG. 7 is a diagram of a modified control circuit operable to effect setting of the thread guide for the sequential knitting of unlike garment components.
  • FIG. 8 is a diagram of a control circuit different from that shown in FIG. 2.
  • control mechanism of the present invention can be used with any known drives for limiting movement of a thread guide in straight-bar knitting machines, such as by relocatable stops chain and sprocket adjustment, or cam surfaces.
  • the invention is described herein in connection with a feed screw and carriage which is usually provided in straightbar knitting machines for setting stops limiting movement of the thread guide.
  • FIG. 1 only the thread-guide setting device for the left side of the knitting frame is shown and described in connection with its control mechanism.
  • the setting device for the right side of the frame is identical and may be operated by the same control mechanism or by independent control mechanism of the same type.
  • a carriage 10 is mounted on feed screw 1 and a guide shaft extends through the carriage to prevent its rotation about the feed screw.
  • a bracket 101 for supporting one or more vertically adjustable stops 102. Such stops may engage or be engaged by a portion 103 of one or more thread guides to limit movement of such thread guides transversely of the knitting frame.
  • a sprocket 11 on the feed screw 1 is driven through chain and sprocket 111 by shaft 112 on one side of dog clutch 115. When the clutch is engaged, shaft 112 is connected to be driven by shaft 113 of the reversible servomotor 114.
  • a notched wheel on the feed screw shaft is engageable by a lock bolt 14 having an end complemental to the wheel notches, such lock bolt being normally biased toward the wheel by spring 141.
  • Wheel 140 and bar 14 constitute a lock to prevent inadvertent rotation of the feed screw.
  • Pawls l2 and 13 are selectively engageable with ratchet wheels I20 and 130, respectively, to prevent rotation in a direction opposite that selected by the control mechanism. Selective engagement of one or the other pawl with its ratchet wheel is effected by its cam disk 121 or 131, which cam disk may be operated by the control circuit for motor 1 14 and clutch 1 15 or may be an independently-operated emergency brake for the feed screw.
  • the pawls l2 and 13 may selectively engage with the ratchet wheels I20 and 130, respectively. to actuate the feed screw I, the choice of pawl being effected by means of its cam disks I21 and IJI, respectively. controlled by any known control device (not shown).
  • a track is mounted by spacers 154. Such track supports signal-blocking member 16.
  • the track is calibrated so that the appropriate edge 160 or 161 of blocking member 16 can be preset to interrupt movement of carriage in a position corresponding to a given position of the thread guide relative to the knitting frame.
  • the blocking member is locked in its preset position by a catch 162 received in one of the notches 155 in the side of track 150.
  • a bracket 104 on carriage 10 carries a photoelectric cell 181 as an example of means for receiving a nonmechanical signal.
  • a further bracket 18 on the carriage carries a light source 180 as an example of means for generating and emitting a nonmechanical signal, spaced above and located to direct a light beam onto photoelectric cell 181.
  • the light source and cell therefore, are fixed relative to each other, but are moved by carriage 10 relative to track 150.
  • the blocking member 16 has a tongue 160, 161 extending beyond track 150 toward the carriage so that such tongue can be interposed between light source 180 and photoelectric cell 181 to block the light beam by movement of the carriage.
  • the knitting machine is programmed to knit a particular garment component successively. Of which the left edge needle of the machine needle bed in its last row is closer to the knitting frame center than it is for its initial row of the previously completed component, so that the carriage 10 would be located to the right of signal-blocking member 16.
  • the program for the knitting cycle would effect energization of the motor 114 and clutch 115 upon completion of the garment component.
  • the motor shaft would rotate in a counterclockwise direction as viewed from the left of FIG. 1, as set by motor direction switch 19 on frame 15, to move the carriage to the left toward blocking member 16.
  • the light signal from the source 180 would be interrupted as soon as the right edge 160 of member 16 is interposed between the signalling means light source and photoelectric cell components 180, 181.
  • the carriage would be located initially to the left of blocking member 16 and switch 19 would be set in its opposite position to reverse motor 114 for turning screw 1 in the counterclockwise direction to drive carriage 10 to the right of FIG. 1.
  • the left side 161 of member 16 would effect interruption of the signal from light source 180 to cell 181.
  • FIG. 2 The control circuit for motor 114 and clutch 115 is shown in FIG. 2.
  • a primary switch 2 is closed by a cam 200 driven by cam shaft 20 at a time corresponding to the completion of knitting of one garment component. Such cam shaft would be actuated in accordance with the programmed cycle in a known manner. Closing'of switch 2 simultaneously energizes light source 180, clutch 115 and solenoid 22 for closing normally open switch 220 to energize motor 1 14.
  • the signal means including light source 180 and photoelectriccell 181 constitute a secondary switch in the control circuit acting through amplifier 21 to maintain energization of solenoid 22 and clutch 115.
  • Such secondary switch is closed by energization of light source 180 upon closing primary switch 2. If motor 114 is driven in a direction to move carriage 10 to the right as seen in FIGS. 1 and 2 until the edge 161 of blocking member 16 interrupts the light beam source 180, switch 180, 181 is opened to deenergize clutch 115 and sole- I noid 22 to open motor circuit 220, thereby stopping the carnage.
  • the photoelectric cell and light source may be mounted on the machine frame in horizontally spaced locations directed toward carriage 10 so that a light beam from the source 180 would strike a reflector strip to be reflected onto cell 181.
  • the secondary switch would be opened as soon as the reflector strip moves into a position to reflect the light beam onto the cell.
  • the light source and cell would be relatively moveable so that the position of the carriage in which the reflector strip actuates the cell can be altered. It would also be possible to locate one of members 180 and 181 of the signalling device on the carriage and the other on the stationary track 150, in which case the secondary switch would be opened when the light beam and the cell are shifted relatively so that the light beam shines on the cell.
  • a second solenoid 22 would be connected in circuit with the first to reverse the polarity of motor 114 in a known manner.
  • Alternate actuation of one or the other solenoid would be effected by moving double-throw switch 19 shown in FIG. 1.
  • Such actuation of switch 19 could be effected manually, or automatically such as by limit switches actuated by the carriage in its extreme positions. Automatic reversibility of the carriage 10 would be desirable, for example, to reset the carriage for later operation.
  • FIG. 6 a modified form of the signal-blocking member 16 is shown.
  • slides 163 and 164 are mounted in a groove 165.
  • the positions of the slides can be adjusted by sliding them in such groove and then fixing their positions by bolts or set screws 166 in slots 167.
  • Calibration 168 on the slides can be set relative to indexes on member 16 to determine the proper location of the slides in their groove.
  • the projecting ends of slides 163 and 164 rather than edges and 161 of member 116 would effect blocking of the light beam signal onto the photoelectric cell.
  • screws 166 may have eccentric shanks so that the slides would be moved along groove simply by turning the screws.
  • Such auxiliary slides may utilize a scale having finer calibrations than the scale on track 150, or such slides may be calibrated for adjustment corresponding to the different needle sizes.
  • FIGS. 3, 4 and 5 show alternative types of devices for receiving nonmechanical signals-which may be used in place of the photoelectric mechanism previously described, and companion devices for generating and emitting nonmechanical signals capable of being received by such receiving devices.
  • a nozzle 24 directs an air jet into cylinder 240 for holding piston 241 in the upper position shown so that the free end of the piston rod 242 engages a switch arm 243 to hold it in engagement with the upper switch contact.
  • spring 244 presses the switch arm into engagement with the lower contact to energize motor 114 and clutch 115.
  • the blocking member 16 could be mounted for movement with the carriage if desired. Naturally with a corresponding formation of the air pipes, suction can be used to control the switch arm 243.
  • a split ring electromagnet 23 produces a magnetic field including an eddy flow adjacent to its ends. Closing of the primary switch 2 energizes the field-inducing winding 230 in place of light source 180. Current induced by transformer effect in the secondary winding 231 closes the secondary switch of the control circuit. When the blocking member 16interrupts the eddy field 232, secondary winding 231 is deenergized and the secondary switch is opened to deenergize the motor and clutch.
  • the light source, photoelectric cell and blocking member of FIG. 1 may be replaced by a photoelectric counter such as shown in FIG. 5.
  • a disk 3 keyed to the shaft of feed screw 1 includes a circular row of apertures 30.
  • the spacing of two adjacent aperatures corresponds to the distance of two adjacent needles in a row transversely of the knitting frame, so that carriage 10 will move a distance corresponding to the. spacing between two adjacent needles while disk 3 is indexed between adjacent apertures 30.
  • a light source is located on one side of disk 3 and photoelectric cell 181- is located on the opposite side of the disk so'that the light beam is directed parallel to the axis of rotation of the disk and is'spaced from such axis a distance equal to the radius of the circular row of apertures 30.
  • the light beam to the photoelectric cell is interrupted periodically to transmit signal pulses through cell 181 and amplifier 21 to counter 216.
  • the counter will in turn actuate the multiple-switch bank 217 to energize and deenergize clutch 115 in accordance with a preset program stored in the counter 216 by means of punch cards or magnetic tape, for example*.
  • the number of signal pulses caused by the rotation of the screw 1 is a measure of the setting distance. It is therefore of no importance how often the disk 3 rotates with the feed screw 1 during the setting ot'the stops 102.
  • disk 30 may have slits or peripheral notches or reflector plates spaced circumferentially of the disk.
  • the light source 180 would be on the same side of the disk as cell 181.
  • the precise location of the apertures in disk 3 can be set to correspond to the spacing of the needles by providing a second disk adjacent to and coaxial with disk 3, so that one disk is provided per setting direction. By turning the disk against the corresponding setting direction, the apertures 30, slits or peripheral notches are also moved in this direction and the interruption point for the setting movement of carriage is corrected.
  • the counter control device could be used with the signal device shown in FIG. I.
  • the blocking member 16 would be elongated and would have a serrated edge which would pass between the light source 180 and cell 181 to produce the pulsating light signals to the cell.
  • Carriage 10 can be actuated by the control circuit shown in FIG. 7 to set thread-guide stops 102 at the beginning of knitting of each of successive dissimilar garment components, such as a sweater front, back and two sleeves.

  • the control circuit for such signalling sets is shown in FIG. 7.
  • the primary switch for this circuit is a four-contact stepping selector switch 190, the contacts of which are connected respectively to light sources 180, 183, 185 and 187.
  • Photoelectric cells 181, 184, 186 and 188 are connected in parallel to energize motor 114 and clutch 115 through amplifier 121.
  • the four light sources and cells move with the carriage relative to the respective tracks 150, 151, 152, and 153 each time carriage 10 moves, but only one of the light sources will be energized at a time corresponding to the position of switch arm 190.
  • switch arm 190 After the completion of one garment component, switch arm 190 would be moved to engage the next adjacent contact to actuate the next light source in the series. After the four components have been made, switch arm 190 can be automatically reset to engage the first contact and the complete cycle can be repeated.
  • the initial setting for the first garment component is made on track 150

  • Switch 19 will be set to energize motor 116 to turn in the desired direction for moving carriage 10 towards blocking member 16 when a primary switch, such as switch 2 shown in FIG. 2, is engaged to close the control circuit. Closing of the control circuit will effect energization of light source 180, and motor 116 will be energized simultaneously to drive the carriage in the direction set by switch 215.
  • both cells 181 and 182 will be deenergized to effect reversal of the motor circuit polarity and reenergization of motor 116 to drive the carriage to the left until it reaches position 16 and cell 182 is again energized, at which time the motor will again be deenergized If the carriage should again overtravel, this time toward the full-line position of member 16, so that both cells 181 and 182 are energized, the motor circuit polarity will again be reversed through the reversing action of mechanism 214 and the motor energized to drive the carriage to the left. This hunting process will continue until the carriage stops in an equilibrium position with the blocking member in position 16.
