Abstract: 1480645 Carrying wound laps to combers TOYO BOSEKI KK 17 July 1974 [20 July 1973] 31690/74 Headings D1F and DIN An automatic apparatus for supplying laps from at least one lap forming machine to lap stands of a group of combers comprises:- an overhead conveyor having lap carriers and bore bobbin carriers; means for lifting a lap received from a lap forming machine to a lap carrier and being adapted to release a lap to a carrier when a detector detects the arrival of an empty lap carrier; raisable and lowerable support means to receive a lap released from a carrier apon a signal from a detector, and to lower and drop the lap on to a lap stand; and means for automatically controlling the sequential operation of the lifting means and lap carriers, and of the support means and lap carriers.  General arrangement-Fig. 1. A lap package wound at 4 is lifted by lifter 2. picked up and carried by carrier 13 guided by endless rail 9 and moved by endless chain 10, and dropped into a supply device 3. of a comber 5 and lowered to a lap supply stand 6. An empty bobbin is manually loaded at a comber onto a similarly guided and moved carrier 14, and released into hopper 7 of lap former 4. Lap package-winding and doffing-Fig. 2. Web 22 is wound on bobbin 20 supported on pivoted arms 19 and rotated by roller 17. The package is released onto rollers 25a, b, the web is cut by cutter 26, and the bobbin is doffed by rotating the rollers about shaft 25d. Lifting package to carrier-Fig. 2. The package is received on rollers in plate 27. Hydraulic ram 38 raises guide 30 in pillar 28, and anchored chain 34 attached to plate 27 causes the plate to rise up the rising guide 30. One of the rollers in plate 27 is rotated by a rack on guide 30 to wind up lap end 24.  Package carrier-Fig. 11A. Each carrier depends from chain 10, has rollers for guidance by rail 9, and has arms 78 pivotable about pin 79 so that jaws 85 may enter a bobbin. Photoelectric detectors 16a, 16b detect the presence of a carrier and of the absence of a lap in the carrier. A member 95 having a V- shaped locating notch is moved by a solenoid to locate carrier rod 76. The chain is stopped using a solenoid-operated clutch. Pin 102 is extended by solenoid 101 and is moved by solenoid 97 to pivot arms 78 to engage the bobbin on lifter plate 27. Supplying package to comber-Fig. 17. At a comber 5, the arrival of a carrier carrying a package is detected by a detector 15 (Fig. 1), and the package is dropped onto a member 122 which is raised and lowered by a chain and which has curved, package-supporting plates. The plates are mounted on pivotable arms which are cammed apart in the lowered position so that the package falls between the plates onto rollers. Three roller-supported laps 23 are fed simultaneously to the comber. A package delivered to the central rollers may be rolled to one of the other two positions. Bobbin carrier-each comprises a horizontal rod. At hopper 7, Fig. 1, the arrival of a carrier carrying a bobbin is detected by a detector, the chain is stopped, the bobbin is lifted by a hydraulic jack, the rod is advanced by the chain and withdrawn from the bobbin and the bobbin is dropped into the hopper. Control. The actuators and solenoids are connected to an automatic control system.
