Aufgabe der Erfindung ist es, ein Verfahren zum kontinuierlichen Stapeln von Zuschnitten aus einer Presse, die in Hubfolge auf eine Förderstrecke abgelegt werden, wobei die Förderstrecke aus zwei hintereinander angeordneten, endlosen Förderbändern mit je einer Stapelmaske zur Aufnahme der Zuschnitte besteht, und die Bandantriebe elektronisch gesteuert sind, sowie das hintere Förderband gleichzeitig als Wippe gestaltet ist und mit dem vorderen Förderband in Wirkverbindung steht, zu schaffen, die ein fortlaufendes Stapeln der Zuschnitte ermöglicht und bei der die Zuschnitte beim Stapelvorgang nicht deformiert werden.The object of the invention is a method for the continuous stacking of blanks from a press, which are stored in a stroke sequence on a conveyor line, wherein the conveyor line of two arranged successively, endless conveyor belts, each with a stack mask for receiving the blanks, and the belt drives are electronically controlled, and the rear conveyor belt is simultaneously designed as a rocker and is in operative connection with the front conveyor, to create, which allows a continuous stacking of the blanks and in which the blanks are not deformed during the stacking process.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass
- a) an einem Messpunkt (S1) über einem
vorderen Förderband
(
1 ) die Durchlaufzeit (t1) von der Vorderkante (VK1) bis zur Hinterkante (HK1) eines Zuschnittes (2 ) und die Durchlaufzeit (t2) von der Vorderkante (VK1) des Zuschnittes (2 ) bis zur Vorderkante (VK1') eines folgenden Zuschnittes (3 ) auf dem vorderen Förderband (1 ) gemessen wird; - b) aus der Differenz von der Durchlaufzeit (t2) und der Durchlaufzeit (t1) eine Lückenzeit (tL) ermittelt wird;
- c) am Ende des ersten Förderbandes
(
1 ) ein Sensor (S2) und am Ende des zweiten Förderbandes (4 ) ein Sensor (S4) angebracht sind, die zum Stapeln der Zuschnitte (2 ) in die jeweilige Stapelmaske (5 ;6 ) am Ende der Förderbänder (1 ;4 ) durch die Vorderkanten (VK1; VK2) der Zuschnitte (2 ) eine elektronische Steuerung des jeweiligen Bandantriebes auslösen, wobei die jeweilige Bandgeschwindigkeit so verringert wird, dass der Energiebetrag der Zuschnitte (2 ) nicht mehr zur Deformationen der Zuschnitte (2 ) beim Stapelvorgang ausreicht; - d) in einer Auswerteeinheit (A) eine funktionsbedingte Lückenzeit
(tF) der Presse (
7 ) mit der ermittelten Lückenzeit (tL) verglichen wird, wobei zur Freigabe des Folgehubes der Presse (7 ) die ermittelte Lückenzeit (tL) größer sein muss als die funktionsbedingte Lückenzeit (tF); - e) über
dem zweiten Förderband
(
4 ) ein Messpunkt (S3) angebracht ist, der die Durchlaufzeit (t3) von der Vorderkante (VK2) des vorderen Zuschnittes (2 ) bis zu der Vorderkante (VK2') des folgenden Zuschnittes (3 ) misst; - f) in der Auswerteeinheit (A) die ermittelte Durchlaufzeit (t3) mit der ermittelten Lückenzeit (tZ)
verglichen wird, und die Bandantriebe für die Förderbänder (
1 ;4 ) elektronisch so gesteuert werden, dass das hintere Förderband (4 ) stets schneller läuft als das vordere Förderband (1 ) und - g) in der Auswerteeinheit (A) die Durchlaufzeit (t3) mit der Lückenzeit (tL) verglichen wird, wobei zur Schaltung der Wippe die Lückenzeit (tL) größer sein muss als die Durchlaufzeit (t3) bei der Messstelle (S3).
- a) at a measuring point (S1) above a front conveyor belt (
1 ) the passage time (t 1 ) from the leading edge (VK1) to the trailing edge (HK1) of a blank (2 ) and the passage time (t 2 ) from the leading edge (VK1) of the blank (2 ) to the leading edge (VK1 ') of a following blank (3 ) on the front conveyor belt (1 ) is measured; - b) a gap time (t L ) is determined from the difference between the cycle time (t 2 ) and the cycle time (t 1 );
- c) at the end of the first conveyor belt (
1 ) a sensor (S2) and at the end of the second conveyor belt (4 ) a sensor (S4) are mounted, which is used for stacking the blanks (2 ) into the respective stack mask (5 ;6 ) at the end of the conveyor belts (1 ;4 ) through the leading edges (VK1, VK2) of the blanks (2 ) trigger an electronic control of the respective tape drive, wherein the respective tape speed is reduced so that the energy amount of the blanks (2 ) no longer for the deformations of the blanks (2 ) is sufficient in the stacking process; - d) in an evaluation unit (A) a function-related gap time (t F ) of the press (
7 ) is compared with the determined gap time (t L ), wherein to release the following stroke of the press (7 ) the determined gap time (t L ) must be greater than the function-dependent gap time (t F ); - e) above the second conveyor belt (
4 ) a measuring point (S3) is attached, which determines the passage time (t 3 ) from the front edge (VK2) of the front blank (2 ) to the leading edge (VK2 ') of the following blank (3 ) measures; - f) in the evaluation unit (A), the determined cycle time (t 3 ) is compared with the determined gap time (t Z ), and the belt drives for the conveyor belts (
1 ;4 ) are controlled electronically so that the rear conveyor belt (4 ) always runs faster than the front conveyor belt (1 ) and - g) in the evaluation unit (A), the cycle time (t 3 ) with the gap time (t L ) is compared, wherein for switching the rocker, the gap time (t L ) must be greater than the cycle time (t 3 ) at the measuring point (S3 ).
