Abstract
In an apparatus and a method for the manufacture of perforated plaster boards, provision is made for the operations of punching and cutting the sides to take place one directly after the other with the boards being held in position by grabbing and conveying equipments during the entire working time.
Claims5
An apparatus for the manufacture of perforated plaster boards, comprising a punching device (6) for applying a perforation and cutting stations for cutting the sides of the boards, wherein
- a first grabbing and conveying equipment (15) with grabs (16) for seizing a non-perforated plaster board (14) by a first side (17), for inserting the plaster board (14) into the punching device (6) and for holding the plaster board (14) during the punching operation;
- a second grabbing and conveying device (18) with grabs (22) for seizing, by a second side (19) opposite the first side (17), a plaster board (14) that has been perforated in the punching device (6), the first grabs (16) being released only after the second grabs (22) have seized the respective plaster board (14), and the second grabbing and conveying equipment (18) leading the respective plaster board in a first conveying direction through a first cutting station (8) where two opposite sides (17, 19) of the plaster board (14) are cut to size;
- a third grabbing and conveying device (25) for seizing the plaster board (14), downstream of the first cutting station (8), by a side (17) that is displaced by 90° as compared to the side (19) seized by the second grabbing and conveying equipment (18), the second grabs (22) being released only after the third grabbing and conveying device (25) has seized the plaster board (14), and the third grabbing and conveying equipment (25) leading the plaster board (14) through a second cutting station (12) in a second conveying direction (11) perpendicular to the first conveying direction (7), with second sides being cut to size that are perpendicular to the sides cut to size in the first cutting station (8).
A method of manufacturing perforated plaster boards on an apparatus comprising a punching device for generation of the perforation and cutting stations for cutting the sides of the board to size, wherein
- by means of a first grabbing and conveying equipment (15) with grabs (16), a non-perforated plaster board (14) is seized by a first side (17), inserted into the punching device (6), and held during the punching operation;
- by means of a second grabbing and conveying device (18) with grabs (22), a plaster board (14) that has been perforated in the punching device (6) is seized by a second side (19) opposite the first side (17), the grabs (16) being released only after the second grabs (22) have seized the respective plaster board (14), and the second grabbing and conveying equipment (18) leading the respective plaster board (14) in a first conveying direction through a first cutting station (8) where two opposite long sides (23, 24) of the plaster board (14) are cut to size;
- by means of a third grabbing and conveying device (25), the plaster board (14) is seized by grabs (26), downstream of the first cutting station (8), by a side of the board (14) that is displaced by 90° as compared to the side seized by the second grabbing and conveying equipment (18), the second grabs (22) being released only after the grabs (26) of the third grabbing and conveying device (25) have seized the plaster board (14), and the third grabbing and conveying equipment (25) leading the plaster board (14) through a second cutting station (12) in a second conveying direction (11) perpendicular to the first conveying direction (7), with second sides (17, 19) being cut to size that are perpendicular to the sides (23, 24) cut to size in the first cutting station (8).
