Abstract

1334359 Grinding TURNER MACHINERY Ltd 15 Dec 1970 [16 Sept 1969] 45560/69 Heading B3D Apparatus for grinding a bladed cylinder 20 mounted for rotation about an axis comprises means for advancing a grinding member 14 towards the cylinder into the path of outer portions of the blade or blades 22 of the cylinder in a series of steps, and control means for controlling the time interval between successive advances of the grinding member. The bladed cylinder 20 is part of a fleshing or other leatherworking machine having a track 18 formed with bearing surfaces along which a carriage 12 is reciprocated by a stainless steel band 24 secured to the carriage by a clamp plate 26 and bolts 28 and guided over a pair of vertical rollers on the frame of the machine, one of which rollers is driven by a reversible motor. The carriage has a vertical guideway 32 for a supoort member 30 formed with a bearing 38 for a spindle 36 carrying the grinding wheel 14 and a pulley 40 connected by a bolt 52 to a pulley 54 driven by a motor 48 adjustably mounted on the member 30. The member 30 has a nut 60 engaged by a lead screw 130 rotatably mounted on the frame and keyed to a worm wheel 122 engaging a worm 120 on a shaft 64 which is connected by bevel gearing to a shaft 72 having a hand wheel. The shaft 64 is also provided with a ratchet wheel 76 engageable by a solenoid-operated pawl 94. In operation, the carriage 12 is reciprocated by the band 24 and the grinding wheel lowered by rotation of the hand wheel to engage the cutter to continuously sharpen the blades. As the blades shorten and the wheel wears, the wheel may be advanced again by rotation of the hand wheel or by actuation of the solenoid which is in a circuit having a first switch controlled by a timing device and a second switch closed by the carriage at one end of its travel. The timing device is adjustable to vary the interval of time between closing of its switch which is then maintained closed until the second switch is closed so that the wheel is only advanced at the end of the carriage movement. The control means may include a detector for monitoring the condition and cutting efficiency of the blades.
