Title: Article counting methods and apparatus
IPC: G06M1/10
Filed: 1969-06-30
Abstract: 1280311 Photo-electric apparatus SPARTANICS Ltd 30 June 1969 [2 Dec 1968] 32884/69 Heading G1A [Also in Division G4] Articles in a stack are counted by sensing edgerepresenting discontinuities between adjacent articles by an array of sensors having an effective thickness less than that of the articles to be counted. As described the sensors are silicon photovoltaic cells. An area 76 of a stack is illuminated through a lens 74 by a D.C. light source, the axis α 1  being adjustable to give maximum contrast of the edges. A pair of cross-coupled sensors 58, 60 are adjusted by guillotine masks 66<SP>1</SP>, 66<SP>11</SP> and object lens 68 so as to scan a pair of areas 70 lying within the width of one article. The angle of scan α 2  is adjusted for maximum contrast. The output is applied to a high-gain F.E.T. amplifier which clamps to a high or low output, i.e. squarewave, in response to small deviations in brightness from average, whereby the gaps between articles are detected and counted. A number of sensor arrays may be used with automatic subtraction from the count in respect of each array above one. To obtain maximum sensitivity a sensor array 270 may be assisted by a diffraction grating (272) Fig.11 (not shown) and a drum cam (246) which is rotated to move the sensor and lens carriers until the vertical bars observed reduce to a minimum. The drum cam may be driven by a servomotor 320, Fig.13, until the phase-difference between the outputs of a sensor pair 284, 286 reaches 180 degrees. Counting corrugated sheets, Fig.16. Illumination is effected at an angle 6 to the perpendicular and viewing at an angle #, the difference approximating to 10 degrees. The sensor length covers several convolutions to provide a reliable average and may be 3-10 times the object thickness. A measuring head, Fig.17, rests on the side of the stack. Light from source 382 follows path 384, 376, 378 to the sheets and then back through a filter 386 and a lens 358 to sensors 352, 354. A guillotine 360, 362 is adjustable by thumbwheel 364. The apparatus may be used for counting razor blades, credit cards, plastic sheets or can lids. Modifications. Cylindrical lenses may be used. An oscillating sensor Fig.19 (not shown), equivalent to one or more sensor pairs, has a scan equal to the thickness of one or more sheets.

In a belt tensioner comprising a roller 7 mounted on a spring steel arm 2 and engaging a belt 8, movement of the roller in a direction normal to its axis of rotation is restrained by a spring-urged friction damper 14. Bearings 10, 11 in a casing 5 carried by a bracket 4 on the arm 2 support the roller 7, a spring 12 acting through the outer race of the bearing 11 to press the cup-shaped friction damper 14 against a friction surface 1 of a fixed structure. To adjust the force urging the friction surfaces together, which force is always substantially less than the tensioning force exerted by the arm 2 on the belt, the damper 14 may have alternative axial locations in a sleeve 13. Alternatively, the spring 12 may act directly on the damper 14 (Fig. 4, not shown). In Fig. 5, the damper comprises a rivet 17 on the arm 2, which is held between the two arms of a spring clip 18 rotatably mounted on the fixed structure. The friction surfaces may be made of, or coated with, material having a high coefficient of friction.
