Definitions

  • the present invention relates to feeding mechanism for textile machines, and more particularly to a mechanism for conveying and distributing textile fibers to a series of carding or similar textile processing machines.
  • Present systems for supplying and distributing fibers to a line of carding or similar textile machines employ a fiber distribution system through which fibers are introduced into a duct and conveyed by air to the series of machines.
  • each by-pass duct there is a damper which controls the feed of the fibers from the main duct to the individual machine.
  • One object of the present invention is to provide an improved system for supplying and distributing fibers to a plurality of carding machines in which the accumulated distribution line losses occurring in conventional systems are eliminated and more rapid passage of the fiber into the demanding station is achieved.
  • Another object of the invention is to increase the overall distribution line efficiency of a fiber feeding and supply system for a plurality of machines over that achieved with conventional systems.
  • Another object of the invention is to provide a feed and distribution system of the character described which will permit use of smaller ducts, fans, etc. for supplying a given number of machines as compared with conventional feed systems.
  • Another object of the invention is to provide a fiber feeding and distribution system which will permit longer duct runs so as to service an additional number of machines as compared with those which can be served by a conventional system having a fan of equal capacity.
  • a longitudinal duct is positioned over a series of cards, each of which is combined With a fiber feeding device.
  • Each feeding device receives its supply from a condenser which is introduced into a bypass that connects the condenser with the longitudinal duct.
  • a fiber reserve box which is adapted to hold a supply of the fibers or fibrous material that is delivered into the reserve box fromthe condenser.
  • a signal system connected with each reserve box controls the withdrawal of fiber from the main distribution duct into the by-pass through control of the position of a twoway damper.
  • One arm of this damper is in the main distribution duct and a second is in the by-pass duct.
  • the dampers associated with all of the feeding devices are normally in positions where the arms thereof that are in the bypass ducts are closed so that all fiber will flow through the main distribution duct, and none will enter the by-passes.
  • a signal from a reserve box is given calling for fiber, however, the position of the two-Way valve or damper associated with that box is reversed so that the portion of the damper in the main duct is closed and the portion of the damper in the by-ipass duct is opened. Air and fiber will then pass from the main duct through the by-pass duct where the fiber is deposited on the condenser and discharged into the reserve box. The air, now free of fiber, passes directly through the condenser and back into the main distribution duct.
  • the reserve box is full, the signal is automatically given to the two-way valve or damper to return to its normal position so that the fiber and air no longer pass into the by-pass but continue down the main distribution duct to the next unit which demands fiber.
  • the reserve boxes for all units in operation will be filled at one time, so that feed-out of fiber from the main distribution duct will be discontinued until one or more reserve boxes again calls for fiber.
  • the last reserve box to receive fiber is required to clear the main distribution line along with its by-pass duct of fibers.
  • This last reserve box, that is required to clear the feed lines may be the first unit nearest the source of supply, or the last unit, or any reserve box in between.
  • the high level con trol switch for each reserve box is equipped with an adjustable signal delay that assures fiber clean-out of the main distribution duct and of the by-pass duct to that last reserve box before shut-off of supply to the main duct.
  • the main distribution duct has a feed and a return reach.
  • the feed section of the line is connected by by-pass duets with the several condensers associated, respectively, with the several feed mechanisms for the several cards.
  • the exhausts from the condensers are all connected by exhaust ducts to the return reach of the main duct; and the only dampers are in the exhaust ducts that lead to the return reach of the main duct.
  • these dampers are open so that air and fibers flow freely from the supply reach of the main duct to all the condensers. Fibers are deposited on these while the air is exhausted to the return reach of the main duct. The fibers are stripped from the respective condensers and deposited in the respective associated reserve boxes.
  • the return reach of the main duct is connected to a condenser which supplies the opener that is connected to the line of cards so that any fibers carried in the return reach are delivered to the opener to be recirculated again to the main duct.
  • FIG. 1 is a side elevation, partly broken away illustrating one embodiment of the invention and showing a line of cards, the feeders therefor, the longitudinal distribution duct, and the by-passes therefrom which supply the several feeding devices;
  • FIG. 2 is a view on a somewhat enlarged scale showing fragmentarily a portion of the main duct, two by passes, and the feeding stations and cards associated therewith;
  • FIG. 3 is a view on a still further enlarge-d scale showing fragmentarily the main distribution duct, one of the by-passes, the valve or damper controlling the connection between the main distribution duct and the by-pass, and the means for operating this valve or damper;

  • FIG. 9 is a fragmentary section of one of the feeders.
  • FIG. 10 is an electrical diagram illustrating how the last shown embodiment of the invention may be wired to accomplish its purpose.
  • 10 denotes the different units to which the supply of fibers is to be fed.
  • a conventional carding machine 11 and a feeding device 12.
  • 14 is the main distribution line. This is a duct which extends over the tops of all of the units 10 and which is fed with fibers from any suitable source as, for instance, a conventional opener 15.
  • a by-pass duct 16 leads from the main duct 14 to a housing 18 within which there is journaled a rotary screen or condenser 20.
  • This screen or condenser may be of conventional construction and such as shown, for instance, in the Langdon et al. US. Patent No. 2,890,497, granted June 16, 1959, and having a duct disposed diametrally within it through which fiberbearing air is sucked so that the fibers are deposited on the condenser.
  • Each condenser is adapted to be independently driven by its own motor.
  • Each is sealingly connected to its housing 18 by seals 21 and 22, which engage the periphery of the condenser and insure that the air passes through the condenser and that the fibers do not by-pass it.
  • a rotary dolfer 26 mounted in a housing 24 attached to each housing 18 and a portion of which extends into the associated housing 18, is a rotary dolfer 26, which has vanes 28 that, in the rotation of the doffer, dolf off of the condenser the mat of fibers deposited thereon.
  • the doifer is driven from the same motor as the condenser through a suitable drive (not shown).
  • Each dotfer delivers the fibers, which it strips from the associated condenser, into a reserve box 30 which is open at 32 to atmosphere, and which has a limit switch 94 mounted therein to gauge and control the upper level of fibers in the reserve box.
  • the reserve box delivers the fibers into a chute 36 from whence it is fed by a controlled drop into a feeder 12. It includes an oscillating gage 38, which is pivotally mounted in the side walls of the feeder section, and which is actuated by the amount of stock present in the feeder at any given time, an endless creeping delivery apron 40, which introduces the stock to an endless elevating apron 42, and an endless stripper apron 44.
  • the elevating apron 42 has slats and pins on it; and so has the stripper apron 44.
  • a rotary condenser 52 and rollers 54 As the rollers 54 and condenser 52 revolve, they form the fibers into a mat and feed it forward under the roller 56 onto the feed plate 58, whence it is fed by the feed roll 60 to the lickerin 62.
  • the fibers are picked up by the cylinder 64 of the card and carried under the card clothing 66, and then doffed by the rotating cylinder 68, and formed by conventional means into a sliver that is deposited in the can 70, all as described in detail in the Harvey and I ones application above mentioned.
  • the pressure of stock on the gate 38 in the feeder 12 tends to swing the gate to the left in FIG. 2; and when it is swung a predetermined distance to the left it trips a limit switch, similar to the limit switch 292 of FIG. 9.
  • This limit switch controls through a solenoid, or other suitable electrically operated means, a clutch (not shown) which controls the drive to the feed rollers 46 in the reserve box 30.
  • This clutch when opened by such electrically operated means, stops feed of the stock from the reserve box 30 into the feeder 12 until the excess stock between the gate 38 and the apron 42 is reduced sulficiently to allow the gate to swing back by gravity toward its normal position shown.
  • valve or damper pivotally mounted between the main air duct 14 and the associated by-pass 16.
  • This valve which is denoted at 75, has two vanes or arms 76 and 77 and is pivoted in the Y formed at the juncture of the main duct 14 and the bypass 16. Normally it is in the position shown in FIG. 3 with the vane or arm 77 closing the by-pass off from the main duct 14.
  • the valve is operated by a solenoid-operated air cylinder 80 which has a piston 82 reciprocable therein. The piston actuates the piston rod 84 which is pivotally connected with an arm 88 which is secured to the shaft 90 on which the damper 75 is mounted.
  • the apparatus shown in FIG. 1 operates on the principle that a low level senser 92 opens the supply valve 75 and high level senser 94 closes this valve.
  • the associated solenoid (FIG. 3) is energized to shift a pneumatic pilot valve (not shown), that controls the associated piston 82, to swing the double damper from the position shown in FIG. 3, and at the left in FIG. 2, to that shown at the right in FIG. 2, thus connecting duct 16 with duct 14 and stopping flow in main duct 16 beyond this damper.
  • the solenoid 130 is deenergized to return the damper 75 to the position shown in FIG. 3, thus shutting olf feed of fibers to the associated reserve box.
  • Each reserve box is independent in its action.
  • a demanding reserve box located in a prior position along the supply line withdraws the entire fiber flow from the supply line before any following reserve boxes receive any supply.
  • any damper 75 opens to the reserve box of a particular card, it closes the supply line at the same instant.
  • the first reserve box fills quickly since the flow rate of fiber from the main duct should be equal to the total flow rate sufficient to feed all of the cards connected to the system plus an over-supply in flow rate.
  • the damper or valve 75 associated with this first unit closes ofi the corresponding by-pass 16 and allows the fiber to be carried on through the duct 14 to the next unit in the line.
  • This next unit then receives the full supply of fiber from the main duct; and so on until all of the reserve boxes of all the units in the system are filled.
  • the supply of fibers to the main line may then be closed oil as, for instance, by tripping a solenoid clutch that drives the motor in the opener 15 or other means supplying the main duct. This clutch remains open until one of the low level sensers 92 in one of the units 10 signals for fiber.
  • damper or valve 75 may be omitted from the last station in the line as shown in FIG. 1 in the case of the unit 12. Then air is drawn continuously through the condenser of this unit and any fibers remaining in the main duct when the air stream reaches this last station are deposited on this condenser.
  • the system of control shown in FIGS. 1 and 4 will supply the reserve boxes of the several units in a heterogeneous manner, since the output rate of the individual cards may vary due to adjusted flow rates of sliver weights differing from card to card or because individual cards are cut out for maintenance from time to time, and perhaps because of production schedules. Therefore, this system of heterogeneous demand and supply may require two, three, four, or even five cards to be filled at any instant when the low level sensers in these units have their respective dampers 75 open. Further, it is obvious that the reserve boxes associated with units 2, 3, and 4 must be supplied successively before the reserve box associated with the fifth unit can be filled.
  • the reserve box associated with the fifth unit must wait with its signal for fiber On until the three reserve boxes associated with the second, third and fourth units are filled. In order that the reserve box associated with the fifth unit does not starve and kick out there should be a built-in secondary reserve to withstand the prolonged interval while the fifth unit is waiting for supply.
  • Assurance of a continuing sufiicient supply to each reserve box can be obtained by increasing the outflow of fibers from the main line so that the outgoing supply may, say, be 150% of the total require by all eight cards. Such an oversupply will fill the respective reserve boxes fast enough so that the reserve below the low level senser in any one box will supply the needs of the unit associated therewith before that reserve runs out.

  • Individual starter buttons 120 and individual stop buttons 122 are provided for the several motors.
  • Switches 126 are simply conventional thermal overload switches for the respective motors.
  • the low level senser 92 in the first unit activates the associated relay to move switch arm 92' of the relay to closed position and activate solenoid-operated clutch 106" to cause the motor 106 to drive the apron 17 in the opener 16 through a belt, chain or gear drive (not shown). Simultaneously the motor 102 will drive, through a belt, chain or gear drive (not shown), the toothed roll 21 to move fiber from the opener into the main line 14. The low level senser 92 will also close the circuit to the solenoid (FIG.
  • the fiber continues to flow into the reserve box of the first unit until it level reaches the high level senser 94. Then the two-position relay switch deenergizes associated clutch 106" and associated solenoid 130 to close off the by-pass and open the main trunk line 14 again.
  • an adjustable time delay relay (not shown) is inserted in the circuit to the high level switch so that there is sufficient delay before shifting of the pilot valve to permit the main trunk line to be cleaned of fiber.
  • the low level senser is deactivated until the high level senser is uncovered by fiber in the reserve box when the double throw switch of the high level senser returns to its normal position.
  • Feed out of the reserve box finally uncovers the low level senser 92. This, in turn, closes the circuit to the low level solenoid 131, and simultaneously the circuit to the clutchconnecting the motor 106 with the apron 17.
  • the feed damper arm 77 opens, and the trunk line damper arm 76 closes, causing fiber to flow from the main line 14 to the reserve box until this supply is again shut oiI by operation of the high level switch 94.
  • the apparatus may be wired, however, as illustrated in FIG. 5.
  • This circuit incorporates a conventional timer switch having multiple adjustable cams for varying the time of its operation.
  • the rotating timer switch 142, 14 etc. is inserted in the valve and feed motor clutch circuits. It is driven by a motor 142 through a conventional interchangeable reduction gear (not shown) so that, for instance, the cam-operated switches 142', 14 of this timer can complete one cycle per minute more or less through the use of change gears between the motor and the switching units.
  • the adjustable cams in the timer will determine the time on and otf for each feed cycle per reserve box.
  • the fundamental difference between the circuit shown in FIG. 5 and that shown in FIG. 4 is that each reserve box has a definite dwell period in each feed cycle as determined by the timer.
  • a high level senser 94 in each reserve box, the feed control functions to hold the reserve box at filled condition.
  • the timer and the adjustable dwell period are set to the condition that the reserve box does not reach a questionable low level in respect to the fiber withdrawn by the associated card in the same period of time.
  • Each reserve box is supplied at a fixed increment of time and in sequence to complete one timing cycle over all the reserve boxes. Should a card be out of service, the high level senser does not activate the feed function and the timer passes on to the next reserve box.
  • the high level switch 94 activates, through the associated switches 94, 94" the solenoid 130 and the clutch 106" between the motor 106 and the apron 17 only when the fiber is below the full level. Further, the feed valve 75 and apron drive clutch act simultaneously and continue the feed until the reserve box is at high level. Then the feed clutch solenoid 106" and the solenoid 130 are deactivated provided, of course, that the timed period is greater than the time required to fill the reserve box.
  • the pilot valve operated by the solenoid 130 returns to neutral by spring force incorporated in the pilot valve control box attached to the air cylinder. This closes the by-pass and opens the main trunk line valve.
  • each reserve box is explored for fiber input in a definite time sequential manner, say each minute more or less, it appears evident that the over-supply of fiber in the trunk line 14 may be limited to between 110% and 120%; and the hazard of heterogeneous supply as for the first-described system of control is overcome. Furthermore, the additional installation of low level senser units in each reserve box is eliminated. In no case will the suction fan be burdened with drawing air through multiple condenser units when two, three, or four reserve boxes are calling for fiber in the heterogeneous manner.
