Abstract: A blank forming system (100) to be installed in a printing process is described. The blank forming system (100) comprises piece ejection system (101) which comprises a cutting unit (105) to cut a web into blanks of defined shape and size. A piece ejector assembly (107) to eject defective blanks from non-defective blanks. An inspection system (103) to monitor web movement through a pair of support rollers (104). A correction system (102) to control the movement of the web through the printing press. Further, the blank forming system (100) also contains a processing unit (108) to monitor and maintain the working of all the other components.
Claims:1. A blank forming system (100) comprising:
a piece ejection system (101) for selectively ejecting blanks, from amongst a plurality of blanks in a printing system, the piece ejection system (101) comprising,
an inspection system (103) to determine speed of a web before being cut into blanks;
a cutting unit (105) to receive the web and cut the web into blanks of a pre-defined shape and size;
a speed measuring unit (106) to measure speed of cutting of web in the cutting unit (105);
a correction system (102) for rectification of errors in web cutting; and
a piece ejector assembly (107) for ejecting defective blanks; and
a processing unit (108) operably coupled to the piece ejection system (101) to,
regulate (307) the correction system (102) to adjust the web movement based on the inputs from the inspection system (103) and through the speed measuring unit (106); and
regulate (308) the piece ejector assembly (107) to eject the defective blanks, based on the inputs from the inspection system (103) and the speed measuring unit (106).
2. The blank forming system (100) as claimed in claim 1, wherein the processing unit (108) synchronizes the web movement through the blank forming system (100) and web cutting process at the cutting unit (105) to within a tolerance limit, based on a data input from the inspection system (103) and the speed measuring unit (106) and a data provided by an operator.
3. The blank forming system (100) as claimed in claim 1, wherein the inspection system (103) inspects the web at a support roller (104) assembly feeding the web to the cutting unit (105).
4. The blank forming system (100) as claimed in claim 1, wherein the inspection system (103) is an Optical Mark Recognition (OMR) system.
5. The blank forming system (100) as claimed in claim 1, wherein the cutting unit (105) is a Rotary Die Cutting (RDC) unit.
6. The blank forming system (100) as claimed in claim 1, wherein the correction system (102) comprises:
a web aligner (102a) to maintain web alignment in the printing press; and
a dancer roller (102b) to control tension across of the web.
7. A method for selectively ejecting blanks, the method comprising:
determining (302) an input speed of a web at an input of a cutting unit (105);
determining (303) an output speed of the web after being cut into blanks;
adjusting (307) a movement of the web by activation of a correction system (102), based on the input speed of a web at the input of the cutting unit (105) and the output speed of the web after being cut into blanks; and
activating (308) a piece ejector assembly (107) based on the input speed of the web at the input of the cutting unit (105) and the output speed of the web after being cut into blanks.
8. The method as claimed in claim 7, wherein the adjusting (307) comprises receiving information inputs pertaining to web movement from the inspection system (103).
9. The method as claimed in claim 7, wherein the adjusting (307) comprises operating the dancer roller (102b) at an input feed assembly.
10. A processing unit (108) comprising:
a determining module (205) to,
obtain an input speed of a web at an input of a cutting unit (105);
obtain an output speed of the web after being cut into blanks;
a response module (207) to,
adjust (307) a movement of the web by activation of a correction system (102), based on the input speed of the web at the input of the cutting unit (105) and the output speed of the web after being cut into blanks; and
activate (308) a piece ejector assembly (107) based on the input speed of the web at the input of the cutting unit (105) and the output speed of the web after being cut into blanks.
