Title: Improvements relating to Tension Control In Material Unwinding Apparatus
IPC: B65H59/04
Filed: 1966-09-29
Abstract: 1,155,874. Feeding webs. SWISS ALUMINIUM Ltd. 29 Sept., 1966 [29 Sept., 1965; 1 Oct., 1965], No. 43530/66. Heading B8K. [Also in Division F2] To maintain the tension constant in a web being fed by rollers 1 from a supply reel 2, the shaft of the reel is coupled to an induction or eddy current brake 3 the pole wheel of which is driven by a motor 5 at a constant speed in a reverse direction to the movement of the brake armature and reel shaft during unwinding, and the current in the coil 4 of the brake is controlled so that the braking effect is adjusted in such manner that the web tension remains substantially constant. The coil 4 is connected via an amplifier 6 to a potentiometer 9 which controls the voltage applied to the coil. Connected to the potentiometer are resistances 10, 11 in series with a tachometer 12 and a D.C. voltage source 13. The tachometer 12 is coupled to the feed rollers 1 and generates a voltage dependent on the speed of the rollers 1. With the reel 2 and rollers 1 stationary, and the motor 5 driving the pole wheel, the potentiometer 9 is adjusted so that the web is under the required tension. When the rollers 1 are started up, the tachometer 12 generates a voltage which causes variation of the current in the coil 4 so that the web tension remains constant as the web speed increases up to its normal value. During subsequent normal running, the voltage generated by the tachometer 12 remains constant. To effect the required adjustment of the coil current as the reel diameter decreases and its shaft speed increases during unwinding, the shaft of the reel 2 is coupled to a tachometer 19 generating a voltage corresponding to the shaft speed. The tachometer 19 is connected to resistances 17, 18 connected to the resistances 10, 11 in such manner that the differential voltage across the two pairs of resistances is applied to the potentiometer 9 to effect the required variation of the coil current. Series-connected mechanically-coupled potentiometers 7, 8 are also in the circuit between the potentiometer 9 and the amplifier 6. The potentiometers 7, 8 are connected, during acceleration or deceleration of the web, by switches 14, 15 respectively to a source of potential so that the coil current is varied to compensate for the acceleration and deceleration forces at the reel shaft. The switches 14, 15 are controlled by acceleration or deceleraton sensitive devices. In a simplified construction, the tachometer 19 and resistances 17, 18 are omitted so that the current in the coil 4 remains constant once the web has reached normal speed. In this arrangement the hyperbolic speed-torque characteristic of the brake causes an approximate adjustment of the brake torque as the reel decreases in diameter, to maintain the web tension substantially constant.

Apparatus for intermittently feeding elongated workpieces 1, 2 &c. to a punch, shear,  drilling machine &c. 4 includes a first pair of rollers 7, 8 upstream of the punch 4, the roller 7 being motor driven and the roller 8 being a pressure roller, a second pair of rollers 7<SP>1</SP>, 8<SP>1</SP> downstream of the punch 4, a measuring roller which may, as shown, be constituted by the pressure roller 8 and which drives measuring means comprising an apertured disc 13, lamp 14 and a photo-electric cell 15 and a known counter e.g. an electronic counter (not shown). Signals from the counter are compared with the desired frequency of e.g. punching along the workpiece and stop the drive to the roller 7, actuate the punch 4 and restart the drive. A brake 11 is mounted on the motor shaft. A microswitch 19 detects the passage of the end of the workpiece 1 and actuates the motor of the downstream pair of rollers to receive the workpiece. If a shearing operation is being carried out at 4 the minimum length of the trailing cut-off end of the workpiece is the distance between the two pairs of rollers.  Instead of a motor and a measuring device being associated with each pair of rollers a single motor may drive a worm engaging worm wheels on shafts of both driven rollers 7, 7<SP>1</SP>, pinions on those shafts engaging pinions on the shafts of rollers 8, 8<SP>1</SP>. A brake and a measuring device 13-15 are mounted on the input shaft of the motor. Alternatively a single motor drives both rollers 7, 7<SP>1</SP> through a worm arrangement and the shafts of rollers 8, 8<SP>1</SP> either each carry a measuring device 13-15 or carry worm wheels engaging a worm with which is associated a single measuring device 13-15. In a further embodiment, Fig. 6, the measuring rollers are distinct from the upstream and downstream roller pairs, each measuring roller 8, 8<SP>1</SP> being associated with a measuring device 13-15 and with a pair of rollers 7, 7a or 7<SP>1</SP>, 7b respectively driven by motors 10<SP>1</SP>, 10.

A male coupling part 10 having an axial bore 10<SP>1</SP> and terminating in a mating end has a shank of given outside diameter and a second diameter portion adjacent the mating end and of greater diameter than the portion of given diameter to define a circumferential shoulder and present an outwardly facing surface 10<SP>11</SP> tapered towards the mating end, and a female coupling part 11 having a bore 11<SP>1</SP> is provided with a corresponding mating end with an axial recess 13 for receiving the mating end of the part 10 and an outwardly extending flange 12 formed with an axially extending circumferential wall 14. Associated with the flange are means independent of the parts 10, 11 for forming an inner circumferential groove 16 opening radially inwardly of the part 11 and containing a sealing member 17 which sealingly engages the tapered surface 10<SP>11</SP>. Means are associated with the groove for locking the connection between the mating ends of the parts and there are means associated with the locking means for releasing the connection; also, there are means for removably mounting the groove forming means and the locking means to the flanged end of the part 11. As shown, a cover 25 screwed on to the wall 14 retains in position an annular plate 15 and the parts are held in the coupled position by a locking ring 18<SP>1</SP> the segments of which are held in assembled relationship by a coil spring ring 24. The ring 18 engages a shoulder 34 on the part 10 and to release the connection a sleeve 29 is slid along the part 10 to radially expand the ring 18. An 0-ring may be housed in a groove formed in the end face of the wall 14. In modifications, (a) the plate 15 is replaced by a ring having a skirt which abuts the flange 12 and an 0-ring is disposed in a groove in the flange and beneath the skirt, (b) the locking ring 18 is replaced by a ring formed with notches for segmental claws urged by leaf springs to project inwardly of the ring. A rim may be secured on the part 10 to prevent accidental movement of the sleeve 29 to the unlocking position. The sealing ring 17 is of resilient plastics material such as rubber, has an outer surface portion 36 of tetrafluoroethylene and is formed with a radial groove 37; the bore of the sealing ring may have fitted therein a coil spring ring.

Abstract: 1,123,353. Mineral mining installations. COAL INDUSTRY (PATENTS) Ltd. 29 Oct., 1965 [29 Oct., 1964], No. 44074/64. Heading E1F. [Also in Division B8] A mine face conveyer 10 of the double or treble strand scraper chain type includes a conveying deck plate 13 which, at each end of the conveyor, rises to guide the chains over a driven sprocket shaft 15. Slide ways 19, 20 support a mining machine (not shown) at the same height throughout including over the end drive sections so that the machine has an uninterrupted path extending from one extreme end of the conveyor 10 to the opposite extreme end. A stage loader 11 is of a double or triple strand roller chain type having contiguous straps extending between and attached to the chains. The receiving end of the loader includes deck plates (25, 26) and its chains are trained around a curved terminal plate (27), Fig. 3 (not shown).. A ramp plate 18 raises loose coal onto the conveyor 10 as the latter is advanced. Transfer of coal from conveyer 10 to loader 11. Three apertures 28 in the deck plate 13 of the conveyor 10 are of a shape and disposition to ensure even distribution of small coal across the loader 11. Coal which is too large to pass through the apertures 28 is deflected onto the loader by a removable deflector 29 mounted on a pivotable base plate 32. When the mining machine is to traverse this section of the conveyor 10, the deflector 29 is removed and the plate 32 pivoted to the position indicated in chain lines. In modifications illustrated in Figs. 5, 6 (not shown), the terminal means (27) do not project into the path of the mining machine since they are mounted wholly within the width of the conveyor (10).
