Definitions
- the invention pertains to control systems for such looms whereby loom stoppage may be effected through signals initiated by detecting any one of the common weaving faults, or by power failure at the loom, or manually by operating switches.
- the invention further relates to sensing means for shuttle protection whereby the absence of the shuttle in a shuttle box at a preselected instant of each cycle will signal through the logic system for a loom stop.
- This invention includes a solid-state computer-type logic system for accepting start and stop commands for a fly-shuttle loom and for translating those commands with predetermined timing to start or stop command signals for an electrically operated clutch-brake loom motor.
- the system provides pushbutton starting and stopping, filling break stopping, shuttle protection stopping, power failure stopping, and brake release during loom stoppage.
- the system includes means to avoid a stop signal during insertion of the first pick following a filling break stop when ordinarily the empty shed would signal for stoppage before the shuttle could insert the first pick. Additional means provides a cloth takeup disconnect action automatically upon signal for normal brake release during loom stoppage.
- the logic system is built with Digital Equipment Corporations K-Series Logic Modules, these modules being interconnected to obtain the proper logic functions, however any type logic may be used.
- FIGS. 1 and 2 combined, show the circuitry of the logic system diagrammatically, the two figures being interconnected through wiring numbered 20 to 23;
- FIG. 3 is a rear view in perspective of the right hand shuttle box
- FIG. 4 is'an enlarged view of a portion of FIG. 3 with different perspective
- FIG. 5 is a rear view in perspective of the handwheel end of the loom crankshaft having the timing coils of the invention supported thereon;
- FIG. 6 is a plan view of the opened timing coil casing of FIG. 5 away from the loom;
- FIG. 7 is a perspective view of the takeup release linkage attached to the loom.
- FIG. 8 is a circuit diagram for the takeup release mechanism of FIG. 7.
- FIGS. 1 and 2 show the computertype logic system diagrammatically with the wiring of the two figures being interconnected at points 20, 2!, 22, and 23.
- a control flip-flop 25 is the heart of the control system withall start and stop command pulses being applied to this flipflop, start command pulses from logic gate 26 (FIG. 2) and stop command pulses from logic gate 27 (FIG. 1).
- the output of flip-flop 25 is connected to logic gate 28 which drives the clutch-brake control unit (Shown in FIG. 8).
- a logic 1 signal is required by the control unit to energize the motor clutch solenoid and a logic 0 signal is required to energize the motor brake solenoid.
- a stepdown transformer (not shown) in the unit provides 12.6 volts AC, center tapped, from the line voltage, which is applied to power supply module 29.
- the outputs of power supply module 29 are the 5 volts DC used by the logic system and a pulse (during power turn-on only) which is applied to control flip-flop 25 through a gate expander 30.
- the 0 pulse is used to initialize the state of flip-flop 25 to the Loom Stopped condition and ensures that the output of logic gate 28 will be 0 and the motor brake solenoid energized.
- a start sequence begins when either pushbutton 31 or 32 is depressed. Capacitor 33 will discharge through the pushbutton contacts providing sufficient current flow to break down any oxide filmwhich may have formed on the switch contact surfaces. Resistor 34 connected from 24 volts DC to the pushbuttons 31 or 32 provides approximately 0.1 ampere for the same purpose.
- the 0 generated by the switch closure is applied through a noise-suppression network including resistor 35, capacitor 36 and isolation diode 37 to inverter 38.
- Resistor 39 connected to the input of inverter 38 ensures that a logic 1 is applied to the input when the pushbuttons 31 and 32 are open. Inverter 38 inverts the 0 and applies a 1 to inverter 40 and one input of logic gate 26.
- the output of inverter 40 is normally 1 changing to 0, milliseconds after the 1 is applied to the input, the delay being caused by capacitor 41.
- logic gate 26 will be 0 only when all its inputs are 1. With the loom stopped and all conditions stabilized, all inputs except the input connected to inverter 38 will be 1. When the inverter 38 output changes to 1 during a start pulse the output of logic gate 26 will go to 0. Five milliseconds later the logic gate 26 input connected to inverter 40 changes to 0 causing the logic gate 26 output to change back from 0 to 1. In this manner a 5 millisecond 0 level pulse is formed from a Start pushbutton 31 or 32 command. This pulse is applied to control flip-flop 25 changing its state to the Loom Running condition.
- switches 45 and 46 are connected through the contact-forming capacitor 47 and resistor 48 and through the noise-suppression network including resistor 49, capacitor 50 and isolation diode 51 to an inverter 52.
- a resistor 53 is connected to the input of inverter 52 to insure that a logic 1 is applied when the switches are open.
- the output of inverter 52 will be 0 if either of the two switches 45 or 46 is opened. This 0 is applied to one input of warp stop memory flip-flop 54 and also to one input of gate expander 55 for logic gate 26.
- the 0 input to flip-flop 54 will cause the loom to stop just as though a warp break or a pushbutton stop had occurred.
- FIGS. 3 and 4 a portion of the right-hand end of a loom is shown with a shuttle box generally designated 56. It will be understood that a second shuttle box is in position at the other end of the loom and the inventive mechanism to be now explained is duplicated in that left-hand box. (Not shown)
- the shuttle box '56 is supported at the end of a lay 57 over which a shuttle 58 is propelled in repeating weaving cycles for inserting picks of filling into opened sheds of warp yarns (not shown).
- the rearward wall of the shuttle box 56 is a pivotally supported and inwardly biased binder 59, pivoted at point 60, for impeding the shuttle in ending its flight.
- Binder pickup coils 61 and 62 are secured to the lay 57 with one being beneath each binder 59 near the point of its greatest pivotal movement.
- Fastened to each binder 59 upon its outer surface and in alignment with a pickup coil 61 or 62 is a pole piece 63 formed of steel and having a flat under surface which is movable above and away from the pickup coil 61.
- the pickup coils 61 and 62 are used to sense the motion of the binders 59 as the shuttle 58 traverses the loom.
- the binder When the shuttle is picked from a shuttle box, the binder will pivot slightly as it comes to the rest or empty-box position. By this movement the pole piece 63 will induce a pulse in the coil 61. When the shuttle contacts the binder on the opposite side of the loom, that binder will be forced away from the rest position and its pole piece 63 will induce a pulse in'the pickup coil 62.
- a handwheel 66' is fastened for rotation upon the loom crankshaft 67 which is arranged to complete one rotation per pick or per weaving cycle.
- a cylindrical casing 68 is supported by having the crankshaft joumaled therethrough and is secured against rotation by a radially extending tab 69 restrained in a fixed bracket 70 on the loom.
- a cover 71 which encloses the casing 68 may be fastened as by screws 72.
- a bearing sleeve 73 of the casing 68 is fastened to the crankshaft 67 by a setscrew 74 and carries with it for rotation a magnet 75 outwardly directed.
- FIG. 5 Spaced about the inner peripheral wall of the casing 68 are five coils 75', 76, 77, 78 and 79 each fastened adjacent to the circular path of the magnet 75 as it rotates and each being angularly adjustable relative to the casing 68 by means of circumferential slots 80. (FIG. 5) Each of the five coils is wired into the logic circuitry as in FIG. 1.
- Protection coil 76 will be pulsed by the crankshaft mounted magnet 75 slightly after the moment the shuttle should have arrived at the receiving shuttle box. This moment in a weaving cycle may be preset selectively by adjusting the angular or circumferential position of the coil 76.
- the pulse from coil 76 is applied to transistor 81, which in turn switches the input of inverter 82 to 0 for 10 milliseconds.
- the output of inverter 82 will be a 10 millisecond-long 1 pulse.
- the output of logic gate 27 will be 0 thereby applying a stop command to the control flip-flop 25 when both inputs are at the I level. This can occur only when shuttle coils 61 and 62 fail to set the output of flip-flop 66 to 0. If the input of logic gate 27 connected to flip-flop 66 is 1, which means the shuttle coils 61 and 62 have not been pulsed, and the input connected to inverter 82 is also 1, as will occur every revolution of thecrankshaft 67, then the output of logic gate 27 connected to flip-flop 25 will go to 0 for 10 milliseconds. This pulse will cause flip-flop 25 to change its state from the Run condition to the Stop condition, thereby sending a Stop command through logic gate 28 to the clutch-brake control unit. The final stopped position of the loom depends upon the instant during the weaving cycle that the synchronizing pulse occurs and can be adjusted by changing the position of the coil 76 as explained above.
- flip-flop 66 In the weaving-cycle sequence from picking to boxing of the shuttle, the input of flip-flop 66 will be pulsed twice, once by the binder coil on the picking side of the loom and once by the coil on the boxing side, coils 61 and 62. The pulse from the picking side, occurring first, will cause the output of flip-flop 66 to go to ll, indicating proper boxing. This is an undesirable transmitted to the reset input of flip-flop 66 thus resetting the 5 output of flip-flop 66 to a l. Flip-flop 66 will remain at 1 until the shuttle in entering the receiving shuttle box will trigger either coil 61 or 62 and set flip-flop 66 to 0 and allow flip-flop 2.: to remain in the Run condition.
- a center fork switch 84 is mechanically connected to the filling stop motion (not shown) of the loom and will close upon detection of a filling break by the stop motion.
- Switch 84 is connected through the contact forming capacitor 85 and resistor 86 and through the noise-suppression network including resistor 87, capacitor 88, and isolation diode 89 to the flip-flop 90.
- a resistor 91 is connected to the input of flip-flop 90 to ensure that a logic 1 is applied when the switch 84 is open. The output of flip-flop 90 will be set to 1 when switch 84 closes. This allows rapid detection and retention of a signal from the switch 84, should vibration of the loom cause the filling break detector switch to bounce intermittently after closing.
- the coil 77 and its transistor 92 will be pulsed by the magnet 75 as the crankshaft 67 rotates.
- a millisecond long 0 pulse will be applied to inverter 93 which applies a 1 pulse to one input of gate expander 94.
- Gate expanders 94 and 95 are connected to logic gate 27 to OR expand its NAND function. If both inputs of logic gate 27 or gate expander 94 or gate expander 95 are l, the output of logic gate 27 will be 0. When the input of gate expander 94 connected to flip-flop 90 is 1 by reason of a filling break detector switch 84 closure and the other input becomes 1, as will occur every revolution of the crankshaft 67, the output of logic gate 27 will drop to ii for 10 milliseconds. This will trigger flip-flop 25 to the Loom Stopped condition and a stop signal will go to the clutch-brake control unit.
- Flip-flop 90 will be reset by coil 75 to prevent a false loom stop should the filling break detector switch 34 be Closed when the loom is started. However, any closure of that switch which may occur after flip-flop 96 has been reset will cause a loom stop.
- the circuit for signalling a warp yarn break or for a manual stop is similar to the filling stop circuit.
- a switch closure from either the warp stop motion switch 96, a manual stop pushbutton 97 or 98, or a single-pick switch 99 or 100, will apply a 0 through the contact forming capacitor 101 and resistor 102 and through the noise suppression network including resistor W3, capacitor 194, and isolation diode 105 to the flip-flop 54.
- a resistor 106 is connected to the input of flip-flop 54 to ensure that a logic I is applied when the switches are open.
- the output of flip-flop 54 will be a i. applied to one input of gate expander 95.
- the timing coil 79 will be pulsed by the magnet 75 and through transistor E07 and inverter 108 will apply a 10 millisecond pulse to the other input of gate expander 95. This will cause a 0 output at logic gate 27 thus setting flip-flop 25 to the Loom Stopped condition to stop the loom.
- Flip-flop 54 will be reset when the loom is started by the start pulse from logic gate 26.
- One input of fiip-flop 54 is also connected to inverter 52 to stop the loom when the safety switches 43 or 44 are opened.
- a first pick protection circuit cancels all stop signals from logic gate 27 until the shuttle has been picked from the shuttle box and is in flight across the loom.
- Gate expanders 109, 110, and Ill are connected to AND expand the input of logic gate 27, gate expander 94, and gate expander 95, respectively. All three gate expanders 109, H0 and 111 are connected to the output of flip-flop 112.
- timer H4 whoseoutput will change from 1 to 0, 50 milliseconds after the 0 is applied to the input.
- Timer 114 is connected to the start circuit through gate expander 55 and when its output is 0 will prevent any subsequent start signals from passing through logic gate 26. This is done to prevent a start signal, accidentally applied while the loom is running, from activating the first pick protection circuit which would prevent a necessary stop from occurring until the following pick.
- the output of timer 114 will change to l as soon as the flip-flop 25'output changes to l and will allow a start signal to pass through logic gate 26.
- a circuit for brake release is included and a sequence is initiated by the Safety-Release switches 45 and 46.
- a l is applied to inverter 52 which in turn applies a 0 to flip-flop 54 and gate expander 55 which stops the loom if it is running and prevents any start signal from triggering flip-flop 25.
- timer 125 will change from 1 to 0 three-fourths of a second after the input changes. This 0 is applied to logic gate 28, changing its output to l or the loom Running condition. The three-fourths of a second time delay is necessary to prevent the brake from being immediately released should the Release switch be closed while the loom is running.
- TAKEUP RELEASE It is desirable to disconnect the takeup mechanism during manual operation of the loom to prevent thin or void places in the cloth. This can be done automatically at the time of brake release by the use of an antitakeup solenoid 126 (FIGS. 7 and 8) to release the holdback pawl 127 of the takeup mechanism to prevent the ratchet wheel 128 from advancing as the loom is rotated by hand.
- a fixed link 129 connects the solenoid 126 to a lever'130 pivotally fixed to a shaft 131 which carries the pawl 127.
- the solenoid is wired as shown in FIG. 8 and during normal loom operation switches 43 and 44 are in the Run position whereby the clutch solenoid is connected to the clutch-brake control unit.
- a start delay timer is included in the circuitry of this invention.
- the start delay is initiated when flip-flop 25 changes state from the Run condition to the Stop condition.
- the 1 output of flip-flop 25 is applied to logic gate 132 which is connected to start delay timer 133 and will apply a 0 to timer 133 when both its inputs are 1.
- One input of logic gate 132 is connected to timer 125 to obtain the start delay function when the brake is reapplied after brake-release sequence.
- the output of timer 133 will be 1 and change to 0, 4 seconds after both inputs of logic gate 132 go to l.
- logic gate 134 The inputs of logic gate 134 are connected to control flipflop 25 and timer 133.
- the input from flip-flop 25 will change to 1 when flip-flop 25 goes to the Stop condition; the input from timer 133 will normally be at 1 and change to 0, 4 seconds after the loom stop.
- a 0 from the output of logic gate 134 is applied to gate expander 55 which prevents any start signal from passing through logic gate 26.
- a power failure detection circuit (FIG. 2) is included in which an auxiliary winding on the motor stator (not shown) provides 15 volts AC to a diode 135 which rectiiies the AC voltage to be filtered by a resistor 136 and a capacitor 137. The base of a transistor 138 is connected to capacitor 137 through a current limiting resistor 139.
- the collector of transistor 138 is connected to the 5-volt logic supply through resistor 140 and also to the base of a transistor 141.
- the collector of transistor 141 is connected to the 5-volt logic supply through resistor 142 and also to one input of gate expander 143. (FIG. I)
- transistor 138 With 15 volts AC applied to diode 135, transistor 138 will be forward biased by the voltage stored by capacitor 137. The collector of transistor 138 will be essentially at ground potential, causing transistor 141 to be biased OFF. Since transistor 141 is not conducting, its collector will be at the 5 volt potential applying a 1 to gate expander 143. When the 15 volt potential is removed from diode 135 because of either a power failure or the motor's thermal overload protection, capacitor 137 will be discharged by resistor 144 and the forward bias will be removed from transistor 138. Transistor 138 will turn off thus applying 5 volts through resistor 140 to the base of transistor 141 which will then be forward biased. It's collector will go to ground potential, applying a 0 to gate expander 143.
- capacitor 145 stores sufficient energy for the logic to function for approximately 1 second after the decay of the input power.
- a shuttle for reciprocal movement along said lay in repetitious weaving cycles during each of which the shuttle is transferred from one end of the lay to the other end thereof, a shuttle box formed upon each end of said lay for receiving said shuttle at the ends of the weaving cycles, each said shuttle box having a pivotable member biased inwardly of said box for decelerating the shuttle as it enters the box, a clutch-brake motor anda control therefor for starting, driving and stopping the loom, shuttle protection means for stopping the loom at the end of the weaving cycle if the shuttle is not-properly received in said shuttle box toward which it is traveling during such cycle, said shuttle protection means comprising a pulse inducing element associated with each said shuttle box, each said pulse inducing element being connectedto be actuated by the movement of said pivotable member upon entry of a shuttle into the associated shuttle box and operative when actuated to generate a signal indicative of the entry of said shuttle into said associated one of said shuttle boxes, means operative for a limited period of time toward the
