Definitions

  • This invention relates generally to bobbin handling apparatus and more particularly to an improved system to automatically transfer bobbins from a moving conveyor to a bobbin transfer apparatus and to automatically maintain a preselected supply of bobbins in the bobbin transfer apparatus.
  • Another object of the invention is to provide an automatic article handling apparatus which automatically and efficiently maintains a constant supply of articles in the feed system to an automatic transfer mechanism.
  • a still further object of the invention is to provide a bobbin transfer system in which the supply of bobbins in the feed mechanism to the transfer apparatus is automatically controlled by the number of bobbins in the feed mechanism.
  • FIGURE 1 is a schematic cross-sectional view of the chute feed control mechanism
  • FIGURE 2 is a top view of the lower section of the ⁇ conveyor shown in FIGURE 1;
  • FIGURE 3 is a cross-sectional view taken on line 3-3 in FIGURE l;
  • FIGURE 4 is a blown-up view of the bobbin jam-up mechanism shown in FIGURE 1;
  • FIGURE 5 is a schematic control circuit showing the preferred control circuit for the bobbin feed control mechanism
  • FIGURE 6 is a modification of the control circuit shown in FIGURE 5.
  • FIGURE 7 is a cross-sectional View similar to FIGURE 1 incorporating the modification shown in FIGURE 6.
  • Bobbins, quills, or the like B are delivered from a common supply source, such as a hopper or bin 10 to an endless conveyor belt 12 travelling in the direction indicated by the arrows with the upper belt portion 14 supported on a platform 16 and the lower belt portion 18 supported on the lower platform 20.
  • a common supply source such as a hopper or bin 10
  • an endless conveyor belt 12 travelling in the direction indicated by the arrows with the upper belt portion 14 supported on a platform 16 and the lower belt portion 18 supported on the lower platform 20.
  • ICG conveyor belt 12 delivers empty bobbins B to' a plurality of discharge stations 22 in a manner generally similar to that shown in copending application Ser. No. 143,421, filed Oct. 6, 1961, now Patent No. 3,173,543.
  • Bobbins B are carried on the conveyor belt 12 normal to the direction of movement of the belt between cleat members 24 suitably connected to the belt 12.
  • cleat members 24 suitably connected to the belt 12.
  • selected cleats 24 have apertures 26 provided therein.
  • certain recesses 28 between the cleats 24 have been filled with a cleat member 36.
  • bobbins B are conveyed from the bin 10 on upper belt portion 14 of the endless conveyor 12 between the cleats 24.
  • the conveyor then reverses direction and conveys the bobbins B toward the bin 10 with the bobbins B laying on the platform 20 in the recesses 28 between the depending cleat members 24 to a plurality of discharge stations 22, only one of which is shown for the sake of illustration.
  • the desired amount of bobbins B l is automatically delivered from the lower belt portion 13 to the bobbin feed chute 32 from which bobbins B are supplied to the transfer cone 34.
  • the chute 32 is defined by a pair of side plates 36 and 38 which can be integral with or suitably connected to the side walls 40 of the conveyor system.
  • the back of the chute 32 is formed by a sheet metal member 42 counected between side walls 36 and 38 in any suitable manner.
  • the front portion of the chute 32 is formed by a pair of angle iron members 44 riveted or otherwise secured at 46 to the side Walls 36 and 33.
  • Sheet metal member 42 and members 44 and 46 are flared outwardly adjacent the conveyor 12 in order to more. ⁇ readily accommodate bobbins dropped therein. Openings 48 and 50 are provided in sheet metal member 42 to allow contacts 52 and 54 of microswitches 56 and 58, respectively, to project therethrough for reasons hereinafter explained.
  • arcuiate'angle iron members 60 and 62 are pivotally secured adjacent-side plates 36 andf38, respectively, by a shaft 64 rotatably supported4 between the side'plates 36 and 38.
  • a microswitch 66 is mounted on the side plate 38 with a spring ⁇ loaded actuator 68 rotatably mounted on the shaft 64.
  • Microswitch 66 is electrically connected to the drive means for the transfer cone 34 and the loading station, not shown, so that when the arcuate angle iron members 60 or 62 are pivoted outward away from the chute 32 actuator 63 will be rotated against the bias of spring 70 away from the microswitch 66, thereby breaking the circuit to the transfer cone and loading station drive means in order to stop operation thereof.l t
  • another microswitch 72 is mounted on side plate 3S with a spring loaded actuator arm 74 pivotally supported on rotatably mounted shaft '76 supported in and extending between side plates 36 and 38.
  • spaced tab members 78 and 80 are integrally connected to shaft 76 adjacent the outlet of chute 32 so that in case of jamming of the bobbins in the Chute or between the chute 32 and the transfer cone 34 the jammed bobbins will contact one or the other of the tabs '78 or 80, thereby rotating the actuator arm 74 against the bias of spring 79 away from the microswitch 72 in order to cut oil the power to the drive means for the transfer cone 34 and the loading stations, not shown.
  • Each knife gate 82 consists basically of a rotary solenoid 84, a rotor shaft 86 operated by the solenoid 84 and an elongated blade member 88 rigidly secured to the shaft 86.
  • rotary solenoids 84 are power open and spring return but it is within the scope of the invention to employ power open and power close type of rotary solenoids.
  • a slot 90 is cut in the lower platform to allow bobbins B to drop into the chute 32 when required.
  • the blade members 88 are rotated from the position shown in dotted lines in FIGURE 2 through an arc of approximately 25 to allow the bobbins to fall through the slot 90 into the chute 32.
  • Arcuate portions 92 are also cut out of the lower platform 20 to allow the blade members 88 to be rotated to the position shown in solid lines in FIGURE 2.
  • a photocell 94 and a light source 96 are located upstream of the gate members 82. If the contact 54 connected to microswitch 58 indicates a need for bobbins in the chute 32, photocell 94 receives light from light source 96 at periodic intervals through apertures 26 spaced along the conveyor belt 12 and actuates rotary solenoids 84 to rotate blade members 88 and allow bobbins B to drop into chute 32.
  • the location of the photocell 94, light source 96 and the apertures 26 depends on the number of bobbins that you desire to drop into the chute 32 at one time. In the preferred embodiment it is desired to drop three bobbins into the chute 32. To enhance this operation it is preferred that each series of three bobbins be separated by a distance approximately equal to three cleats. As pointed out previously cleat 30 was provided to fill certain preselected recesses 28. The filling of such recesses provides the preselected distance between each set of three bobbins. This preselected closed area allows time for the gate member 82 to open completely before the first bobbin is dropped into the chute 32 and alleviates the possibility of catching a bobbin between the conveyor belt 12 and the blade member 88. Further, this preselected closed area allows the gate member to close without jamming a bobbin which has been only partially dropped from the recesses 28 into the chute 32.
  • a contact 52 of microswitch 56 is provided in chute 32.
  • FIGURES l and 5 the operation of the system will be explained. Assume for the sake of explanation that the conveyor 12 is moving in the direction indicated by the arrows and that the bobbin supply in the chute 32 is above the contact 54 causing the switch 58 to assume the down position shown in solid lines in FIGURE 5.
  • silicon controlled rectifiers 98 and 100 are employed. Silicon controlled rectifiers 98 and 100 are four layer, three terminal devices with performance similar to a thyratron.
  • the gate terminals 102 and 104 correspond to the control grid of the thyratron in this analogy except that it is current rather than voltage controlled. A few milliamps fed into the gate terminals 102 and 104 at a small positive voltage will turn on the controlled rectifiers 98 and 100.
  • the gate terminals 102 and 104'then lose control and the controlled rectifiers 98 and 100 can be turned off only by removing B-lor by reducing anode current below the holding value. The latter turn off method is used in this circuit.
  • the positive side'of the capacitor 106 is shorted to the cathode through controlled rectifier 100, thereby applying the voltage across the controlled rectifier 98 in the reverse direction.
  • the capacitor discharge current iiows initially through the control rectifier 98 in the reverse direction causing the controlled rectifier 98 to turn off quickly.
  • Capacitor current continues to flow through resistance 108 and controlled rectifier 100 until the capacitor 106 is charged to B-lwith the opposite polarity.
  • microswitch 58 ⁇ will remain in the dotted line position, causing the controlled rectifier to stay on, thereby maintaining the rotary solenoid energized and keeping the blade members 88 in the open position to allow bobbins to drop into the chute regardless of .the number of light pulses which strike the photocell 94 through the apertures 26.
  • FIGURES 6 and 7 is similar to the preferred embodiment of FIGURES l-5 except the microswitch arrangement has been replaced by a solid state switch arrangement in which light source 110, photocell 112 and Zener ⁇ diode 114 replace the contact 54 and microswitch 58.
  • the photocell 112 is so placed to receive light from the light source when the level of bobbins in the chtite 32 drops below a predetermined point.
  • the open contact condition or dotted line position of Vswitch 58 in FIGURE 5 ⁇ for the controlled rectier 98 is simulated by the high impedance of the diode 114 in the blocking condition when voltage at point V3 is less than the breakdown voltage of the diode.
  • the closed contact or solid line position of switch 58 in FIGURE 5 is simulated in FIGURE 6 by the very low breakdown impedance of the diode 114 when the voltage V3 exceeds the breakdown voltage off the diode.
  • the open contact condition equivalent to the solid line position of the switch 58 is simulated 'by the high impedance of the dark photocell 112 land its closed contact condition equivalent to the dotted line .position of switch 58 in FIGURE 5 is simulated by the low impedance of the photocell 112 when energized by the light source 110.
  • the resistance of photocell 112 will then be decreased allowing the gate terminal current Ig to fire the controlled rectifier 100 and energize the spring return rotary solenoid 84 to open the blade members 88 and allow bobbins to be supplied to the chute 32.
  • voltage V3 drops to a value less than the breakdown voltage of the diode 114 so the diode 114 will block the ow of current to the controlled rectier 98, thereby allowing the capacitor discharge current to turn off the controlled rectifier 98.
  • the circuit is now again ready to close off the opening 90 when the photocell 112 is blocked from the light source 110 when the chute 32 has an adequate supply of bobbins.
  • the bobbin system automatically and eiliciently maintains a supply of bobbins in the feed mechanism to a bobbin loading station.
  • Such system does not require the constant -attendance of an operator and provides safety devices to lshut the system down in case of a malfunction.
  • a bobbin transfer mechanism comprising an endless belt, means forming pockets in the outer surface of said endless belt, means supplying bobbins to said pockets, said belt having at least one run in which said pockets open downwardly, belt guiding means operably associated with said one run and preventing said bobbins from dropping out of said downwardly opening pockets, means forming an opening in said belt guiding means of sufiicient size to allow a bobbin to fall through, gate means operably associated with said opening to prevent bobbins from falling through said opening from said one run, bobbin receiving and guiding means located below said opening, means operably associated with said one run, said gate means, and said bobbin receiving and guiding means to periodically open and close said gate means to allow bobbins to be supplied to said bobbin receiving and one run, said gate means, and said bobbin receiving and guiding means including a detecting means in operative relationship with said bobbin receiving and guiding means to detect the absence of bobbins in a certain predetermined area of said bobbin receiving and
