摘要:
A device is provided for supporting plate-shaped materials for at least one separating operation in the plate-shaped material using a separating mechanism that is movable at least in the X direction during a separating operation. The device includes a first supporting table having a first supporting surface and a second supporting table having a second supporting surface. The supporting surface of the first supporting table and the supporting surface of the second supporting table are spaced apart from each other by a gap which is located below the separating mechanism. Each of the supporting tables comprises a separately driven belt conveyor which is guided by a plurality of rollers, each supporting surface being formed between at least two of the rollers which are spaced apart from each other and lie in a plane. The at least two rollers that bound the supporting surface are movable independently of each other in and counter to the Y direction.

The invention relates to a device for accommodating flat materials when separated by laser, water-jet, cutting torch or milling. The slot provided under the separating device is displaced by enlarging one bearing surface and reducing the size of the other bearing surface when the separating device is moved, whereby damage to the bearing surface is reduced when cutting any particular contours. The invention enables separation, targeted sorting of the separated parts and the clearing away of the remaining materials.
摘要:
A travelling slot cutting machine and method of cutting a workpiece upon the machine in which there are two independently operable and longitudinally aligned, endless conveyor belts, the adjacent ends of which are spaced apart to define a gap through which a cutting medium may be directed. To cut a workpiece supported over the gap, the cutting medium is directed through the gap while the cutting machine, as well as the gap, are moved longitudinally relative to the stationary workpiece. In moving the gap, the conveyors are clamped against movement over their respective supporting rollers. The supporting rollers are then moved in such a fashion that the length of at least one of the conveyor belts is maintained unchanged as the workpiece is transported from the upper run of one of the conveyor belts to the upper run of the other conveyor belts.

The invention relates to an arrangement and a method for the separation and removal of plate-shaped workpieces (7) out of the proximity of a separating device, which arrangement and method are intended for the automatic removal of such workpieces. For this purpose a bearing surface (2, 3) of a two-piece supporting table (4) is replaced by a second supporting table (6), which, together with the remaining bearing surface (3, 2), is moved and therein accepts the workpiece (7) completely. The second supporting table (6) subsequently carries the workpiece (7) completely out of the proximity of the first supporting table (4). The arrangement and the method permit separating the workpieces without damage to the support and the rapid and precise removal of the worked workpieces as well as of the trimmings.

An apparatus for cutting a laminated sheet material has a cutter receiving plate and a closure member connected to both ends of the receiving plate, and these are accommodated in a guide groove extending transversely across a supporting surface of a pedestal. A belt is supported on the supporting surface on front and back sides of the guide groove, and belt moving members are disposed on both sides of the belt longitudinally thereof for reciprocating the belt longitudinally. The laminated sheet material is supported on the belt and the belt moving members are moved to transport the belt and the laminated sheet material together in the longitudinal direction, with the stacked sheets and the already cut portions thereof moving along with the belt while carried thereon.

A laminate cutting apparatus has a support belt supported on a frame for reciprocating horizontally in the longitudinal direction, independently lowerable support plates juxtaposed in the longitudinal direction and retained on the frame for supporting the bottom of a laminate support portion of the belt, suction ports on opposing side portions of the frame for withdrawing air from the interior of the laminate supported on the support portion with its upper and lower surfaces covered with air-impermeable sheets, a longitudinally reciprocated travelling body supported on the frame, a transversely reciprocated cutter head supported on the travelling body, a cutter on the cutter head for being raised and lowered to cut the laminate, recess forming rollers for forming the support portion of the belt into a transversely extending movable recess open at the top, a lower receiving member secured to the travelling body and arranged in parallel with the rollers within the recess, interconnected closure plates within the receiving member for reciprocating transversely in synchronization with the cutter head, a cutter receiving sleeve between closure plates for supporting the cutter tip, and cam plates on the travelling body for lowering the support plates to a level below the recess. Upper surfaces of the support portion of the belt, the lower receiving member, the closure plates, and the sleeve are substantially flush.

Sheet material is moved along its length from a supply to a take-up spool and the material is inspected as it is moved. A garment pattern image is projected on and is moved with the material. The operator determines where the material is to be cut either from the length accumulated on the take-up spool or from the image projected on the material, and if a flaw in the material is detected, the operator determines if the flaw should be removed by identifying the pattern part in the garment from the image projected on the material where the flaw will appear. If the flaw is to be removed, the operator cuts the flaw out and splices the cut ends of material together at splice marks in the image projected on the material. The spools loaded with sheet material with this procedure are loaded in a creel, and the ends of the sheets of material from the spools in the creel are aligned in a vertically stacked arrangement and moved to a cutting apparatus where the garment pattern is cut in the stacked sheets of material.

Apparatus for holding sheet material and other objects during cutting or other work thereon includes a vacuum holddown device having a supporting surface including a plurality of vacuum openings passing therethrough. A vacuum chamber associated with the supporting surface applies a vacuum through the vacuum openings to the sheet material or other object or objects received thereon. A sheet or panel of substantially airimpervious sheet material, such as a sheet of thin polyethylene, is spread over the exposed surface of the work and cooperates with the vacuum to draw the work toward the supporting surface and, if it is compressible, into a more compact condition. The air-impervious panel used with the vacuum may be an expendable sheet of such material spread entirely over the surface of the work prior to working thereon and/or may be one or two continuous belts of such material located in front of and/or behind an associated tool. In cases where the work is a layup of garment fabric, the vacuum and air-impervious panel may also be used to hold the layup in a compact condition for a long period of time between the laying up process and the cutting or other work process to prevent the various layers of the layup from shifting, flowing or otherwise moving relative to one another so as to depart from their relative positions as initially laid up.
摘要:
A supporting table with a supporting surface which is variable in size for plate-like materials, with a link conveyor which forms the supporting surface and is composed of individual bearing elements which are mounted at their end sides on a table frame and are guided via deflecting rollers movable along the table frame. The link conveyor has transport chains on both sides with pins protruding on both sides, the pins of an outer chain link being assigned to a bearing element, the pins facing the bearing element being fixed on the bearing element and those pins of a bearing element which face the table frame having a slide, which is movable in the axial direction of the pins, for optional engagement with the table frame.
