DEVICE AND METHOD FOR BREAKING OFF AND SEPARATING FINISHED PRODUCTS

摘要

A device and a method suitable for a sheet punching and embossing machine, is employed for separating finished products and scrap material of a punched sheet while the sheet is moved in a transport direction, with the finished products and scrap material adjoining one another at punching lines. The device includes a break-off element which can be moved intermittently away from a second plane and towards the second plane between a break-off position and a rest position. The application of force onto the scrap material ends before the track of the applied force crosses an unevenly arranged punching line, and the application of force is resumed after the track of the applied force has crossed an evenly arranged punching line.

主权项

1. A device for breaking off and separating finished product and waste product of a punched sheet, which are adjacent to one another on punching lines, while the sheet is moving in a conveying direction, in particular for a sheet-fed punching and embossing machine, comprising
a first conveying unit for inward conveying of sheets along the conveying direction in a first plane at a first speed, having a continuous first belt, which is guided along deflection rollers, and a holding-down means, wherein the holding-down means is pushable onto the first belt, at least one breaking-off means for breaking off finished product from the sheet, wherein the at least one breaking-off means, in a second plane which is not parallel in relation to the first plane, is pushable onto the first belt, a first drawing-off means for outward conveying of the waste product which is separated from the finished product in the second plane, wherein the first drawing-off means is pushable onto the first belt, and a second conveying unit, for outward conveying of finished product at a second speed in a third plane which is not parallel in relation to the second plane, having a continuous second belt which is guided along deflection rollers, and having a second drawing-off means, wherein the second drawing-off means is pushable onto the second belt, wherein the breaking-off means is movable in a clocked manner between a breaking-off position and a rest position, away from the second plane and toward the second plane.
