Abstract: 1,151,341. Coiling Wire. FURUKAWA ELECTRIC CO. Ltd. 15 April, 1966 [19 April, 1965 (2); 20 April, 1965; 24 April, 1965; 15 July, 1965; 22 Sept., 1965; 7 Oct., 1965], No. 16585/66. Heading B3E. [Also in Division B2] A wire accumulating apparatus comprises a cage 26 which is equipped with a plurality of endless belts 31 arranged to form a hollow cylinder about a shaft 27 and as the shaft rotates the cage 26 rotates and the endless belts revolve in the lengthwise direction of a shaft. Thus as the cage 26 revolves round the axis of a shaft 27 the rotation is transmitted to a pulley 30 through a differential gear reduction device 28 and a bevel gear 29, pulley 30 rotates and the belts 31 move in the direction of the arrows. A wire 3<SP>1</SP> is wound up on the cage 26 which is revolving and due to the function of the belt 31 which is moving, the wire 3<SP>1</SP> is conveyed on the cage 26 in order from the inlet to the outlet. The tension in the wire can be regulated by varying the torque applied to the shaft 27. An apparatus for coiling wire consists of a shaft 37, mounted for rotation in a bearing box 39 of machine frame 38 and driven by a motor through transmission gears by means of the pulley or the gear 40 provided at the end of the shaft. Wire is fed from the back end of the shaft 37 through the bore 41 of the shaft and passes round the guide wheels 43 and 43<SP>1</SP> to the flyer 42 mounted on the shaft 37. Concentric gears 44 and 44<SP>1</SP> of the same diameter are fitted at both ends of the shaft 45 supported on the flyer 42, parallel to the shaft 37. One of the gears 44 engages with the gear 46 fixed at the end of the bearing box 39 of the machine frame 38 while the other 44<SP>1</SP> engages with the gear 48 fixed in the end of a bore in insert 47<SP>1</SP> of a stationary body 47 surrounding part 37<SP>1</SP> of the shaft 37. The conveyer belts 49 disposed about the body 47 are stretched between the pulleys 50 and 50<SP>1</SP>, between them is a tension adjusting pulley 51. At the top of the crank-arm 52 fixed at the extended part 37<SP>1</SP> of the shaft 37 there is a crank-pin 53 mounted to turn freely. At both ends of the crank-pin there are fixed epicyclic gears 54 and 54<SP>1</SP> respectively of different tooth numbers, one of which 54 engages with fixed gear 55 formed on insert 47<SP>1</SP>, while the other 54<SP>1</SP> engages with the gear 57 formed on the tube 56. The arrangement is such that rotation of the shaft 37 causes the tube 56 to rotate with extremely low speed. Bevel gear 58 is formed at the end of the tube 56 and drives bevel gear 59 at one end of the shaft 60, which at its other end carries a gear 61. The gear 61 meshes with a further bevel gear 62 secured to the shaft which carries the conveyer belt pulley 50. A guide 63 is connected with a front end of the body 47, and under the guide 63 a basket is provided for receiving the coiled wire. As the shaft 37 rotates, the wire is pulled out from the centre hole 41 of the shaft and is wound around the conveyer belt 49 by rotation of the flyer 42. At this time the body 47 is stationary. Each of the conveyer belts 49 is simultaneously driven in the direction of the arrow through the bevel gears by the tube 56 which is driven at a low speed due to the turning of rotating shaft 37 through differential epicyclic gear device. The wires wound around the conveyer belts 49 move forward until they leave the belts and slide down around the guide 63 and are received in the basket 64.
