Abstract: A horizontal bandsaw is mounted in a tool carrier above a workpiece location. Before it starts cutting the bandsaw is tilted an angle between 3.degree. and 10.degree. and after the initial cut that angle is maintained during the rest of the cut until the intended depth of cut is reached or closely approached, when the saw tilt is removed as the structure containing the bandsaw is swung to orient the bandsaw horizontally. If the depth of cut is a complete cut through, the advantage of a minimum erosion of the center selvage of the workpiece support is assured. Mechanical limits are provided for the vertical displacement by tilt at one side of the workpiece and on that side one of the guides of the structure supporting the bandsaw has a hydraulic changeover control in which the angle of tilt is set by adjustable screw-stops which cooperate with stop plates mounted on the structure supporting the bandsaw.

Abstract: A shelf service apparatus is provided in the form of a crane for a store for rod-like material accomodated in self-supporting magazines or pallet boxes, where the store comprises shelving units arranged transversely of the storage space and aligned with one another in the direction of the storage space, which units comprise vertical shelf supports (2) with carrier arms (3) secured thereon one above another so as to extend in the direction of the storage space, for the magazines (4). The crane has load supporting forks (12) movable up and down by guide devices (16), with reception brackets (13) by which the magazines can be grasped and moved. To weigh the material in the pallet boxes, a receiver (18) is arranged, with spacing, on the forward portion of the reception brackets (13). The receiver is supported by transverse beams (20) in relation to the reception bracket 13. Weighing cells (20a) are coupled to the beams.

Abstract: To permit miter cuts clear through a workpiece, or for selected depths, a saw band carrier (6) supports a pair of saw band wheels (7, 8) above and below a workpiece support (2), and the saw band wheel carrier (6) is pivotable about a substantially vertical axis of rotation (29). The axis of rotation (29) is preferably located at the initial cutting engagement point of an endless saw band (9) looped about the saw band wheels (7, 8), and the pivoting position can be arrested at any desired pivoted or angular position. In addition, the saw band carrier can be arranged to tilt about an essentially horizontal tilt axis.

Abstract: The invention provides shelf service apparatus in the form of a gantry crane (7), for a material store for rod-like material which may be accommodated in self-supporting magazines (5), where the material store comprises stacking frames arranged transversely of, and aligned with one another in, the storage space direction and separated from one another by lanes for material transport. These frames are provided in the manner of shelving units with carrier arms (4) arranged one above another, extending in the direction of the storage space and secured on vertical shelving supports (2), for the material or the magazines.

Abstract: A goods handling system in which elongated goods such as rails, rods or plates are located in storage boxes or cassettes (12), and in which the storage boxes or cassettes are placed on racks having rack supports (15) above each other, the racks being located in a warehouse-type arrangement, with passageways therebetween. Cranes or hoists (19-23) can transfer the cassettes from a storage location in the racks to a horizontally movable transport wagon, which can transport the cassettes to a utilization station (40), for example for reloading, unloading and the like. A control unit (CU) keeps track of the respective cassettes which are interchanged, at random, in the racks, by placing an empty cassette into a storage location from which a full cassette, on which work is to be done, is removed.

Abstract: A unitary workpiece handling system has a frame (10) which can be operatively coupled to a supply conveyor (1, 4, 5, 6) which transports workpieces to a supply position. Two transfer jaws (17, 18) engage and guide and may grip the workpiece at end faces and, by pivotable mounting and upon pivoting about a pivot axis (20), transfer the workpiece to a receiver (22, 23) which is formed by receiver elements having upstanding portions to define an essentially prismatic configuration therebetween. The receiver is pivotable about a receiver axis (21) to transfer the workpieces to a workpiece gripping system (25) which picks up the workpiece at the end faces and places it on a delivery conveyor (26) or the like, directly or after rotating the workpieces by 90.degree., so that upstanding disk-like elements are laid flat. A plurality of workpieces can be, individually, in the transfer jaws (17, 18), the receiver (22, 23) and the gripper (25) to provide for rapid handling.

Abstract: The clamping device has a stationary, substantially vertical clamping face (5) for the workpiece, arranged at right angles with respect to the feed direction of the saw band. A movable clamping jaw (8) is horizontally movable with respect thereto, the clamping jaw (8) having a substantially vertical clamping face (9). The movable clamping jaw (8) is formed as a clamping bridge (7), reaching over the machine table. The fixed clamping face (5) also reaches over the machine table, while leaving a passage for the saw band. The ends of the clamping bridge are guided horizontally beside the machine bench, for clampable adjustment perpendicular to the clamping faces (5, 9), the clamping bridge (7) being pivotable on guide blocks (22, 23) slidable on guide rails next to and below the table (2) of the saw, so that the clamping bridge can clamp a workpiece (3) between the clamping faces, by a toggle connection to a handle, or release the movable bridge.

Abstract: To provide for efficient handling of stock material (40) and cut-off elements (41), which may be workpieces or cut-off wedges, by a cut-off saw, with miter adjustments, a positioning finger (21) is pressed against the stock material to engage the stock material against a guide plate or bar (19) prior to clamping the stock material in position for cut-off. After cutting of the stock material, the clamp (5) is released, and the finger is moved to a position ahead of the cut-off surface, and then longitudinally in feeding direction to a removal conveyor (28) so that the cut-off element is raked away by the positioning finger. After removal, the positioning finger is retracted out of the path of the stock material and, while new stock material is being fed, is longitudinally returned to the starting position to again align new stock material against the guide plate or bar (19).

Abstract: To prevent formation of burrs and splinters upon sawing a workpiece (3) with a continuously moving saw band (9) operating in a cutting movement direction (18), the saw band (9) is guided at an inclination or angle (19) with respect to a support surface (2) of the workpiece (3) at least just before cut-through, in which the angle (19) is open or away from the support surface, with respect to the cutting movement direction (18). A saw band holder (8) can be tipped or tilted about a pivot axis (7) offset from the support surface, or guided, already initially, at the angle which, preferably, is between about 1.degree. and 10.degree. and, especially, about 3.degree..

Abstract: To permit loading of elongated goods such as rails, rods, strips, or a combination of the foregoing retained in cassettes, from support shelves located on stacks positioned on both sides of a gang way or corridor in which a roller conveyor (13) is located, a frame element (5) carries thereon guide track supports (11, 12) which are positioned in essentially V configuration. Movable support elements, preferably connected by a longitudinal beam, and operated by cylinder-piston units move the goods from a raised transfer position to or from a hoist to a position out of the roller conveyor. The goods can be moved by the hoist from the storage stacks to either one of the support elements which, then, can move on the inclined tracks from the side of the roller conveyor to beneath the rolls of the roller conveyor.

Abstract: An apparatus for handling bar-like workpiece material in a sawing machine, in particular in the form of a miter-box saw, whichhas a clamping carriage that is disposed on the machine frame above the workpiece table and is movable horizontally and parallel to the feed direction of the workpiece material. On one workpiece side, the clamping carriage has two openable and closable bearing jaws, and facing them in the direction of the workpiece material it has three openable and closable clamping jaws disposed beside one another in the material feed direction. The openable and closing jaws are coordinated such that a stock material is held in place for sawing a measured piece and then the cut piece and stock material are moved together to a position for the nextcut length. The cut piece is then moved and released. The steps are repeated to cut the next and successive pieces.
