Abstract

1,183,597. Grinding. K. HEESEMANN. 10 Nov., 1967 [11 Nov., 1966], No. 51302/67. Heading B3D. A method of grinding plate-like large-area workpieces, such as veneered, lacquered or laminated workpieces 52a, comprises first grinding the workpieces transverse to their direction of feed and subsequently parallel to their direction of feed. In apparatus for carrying out the method, workpieces are fed by a conveyer belt 15 past two transverse grinding mechanisms 17, 18 having vertically adjustable pressure beams which are adjustable to the width of the workpieces. Pressure rollers 19 ... 22 are arranged each side of the mechanisms 17, 18 and a contact roller controls the vertical movements of the beams. The belt 15 also feeds the workpieces to a longitudinal grinding mechanism 23 having a belt 34 which grinds the workpiece parallel to its direction of feed and is also reciprocated transversely thereto. The belt is guided over pulleys 32, 35, 36 and a pressure beam 23a which are mounted on a member 30 and plates 28, 29 guided by rollers on a guide 24 at one end carried by an arm 25 from a support 11 and at the other end releasably secured to a pivoted support 26 which is releasable to permit changing of the belt. A reversible motor 42 controlled by limit switches 45, 46 operates through a screw 43 and nut 44 to reciprocate the member 30 and hence the belt while it is driven around the pulleys by a motor 32a. The belt is tensioned by an air cylinder 38 and its tracking is controlled by an air cylinder 40 which moves the drive roller 32 about a universal joint 41. The pressure beam 23a is vertically adjustable by a parallel linkage mechanism controlled by a contact roller in the same plane as pressure rollers 49, 50. The pressure surface of the pressure beam is controlled so as not to grind the edges of the workpiece and consists of a mechanism for adjusting the effective length of the pressure beam and an automatic mechanism dependent on the reciprocating movement of the belt assembly. A guide rail 55 is mounted between vertical guiding devices 54, 56 at the ends of the guide member 24 and the pressure beam 23a is guided for reciprocating movement along the guide rail by rollers. Sliding rails 57, 58 are adjustably secured to the rail 55 and have oblique surfaces 57a, 58a which are adjusted to be adjacent the edges of the workpiece 52a. The rails 57, 58 co-operate with rollers of levers 69 which are thereby rocked and, by means of links 66 vertically displace a portion of a steel plate 65 acting as a pressure member according to the width of the workpiece as the pressure beam assembly is reciprocated with the belt by the motor 42.
