Striping apparatus and striping method
View Patent ↗The present invention relates to a striping apparatus and a striping method. The apparatus for stripping a film from a product comprising a transfer device for transferring the product; a film stripping device disposed above a stripping operation area of the transfer device for stripping the film from the product; and a plurality of guiding devices disposed on both sides of the transfer device in the stripping operation area for guiding the transfer direction of the product.
1. A method for stripping a film from a product comprising the steps of:
transferring the product on a transfer device to a film stripping device; and
stripping the film from the product by the film stripping device,
wherein the transfer direction of the product is guided by a guiding device along a prescribed direction during the steps of transferring the product and stripping the film from the product, and
wherein when the product is transferred to a first position along the transfer direction, the transfer speed of the product is increased from a first speed value to a second speed value and keeps at the second speed value;
when the product is transferred to a second position along the transfer direction, the transfer speed of the product is increased from the second speed value to a third speed value and keeps at the third speed value; and
when the product is transferred to a third position along the transfer direction, the transfer speed of the product is decreased from the third speed value to a fourth speed value and keeps at the fourth speed value.
2. The method according to claim 1 , after the step of stripping the film from the product, further comprising a step of detecting whether the film is completely stripped from the product and a step of transferring the product back for stripping when the film is not completely stripped from the product.
3. The method according to claim 2 , wherein the step of detecting whether the film is completely stripped from the product further comprises the steps of:
detecting whether the film is completely stripped from the product,
clearing a counter device when the film is completely stripped, otherwise increasing a counter value by one and determining whether the counter value reaches a threshold value; and
stopping the transfer device when the threshold value is reached, otherwise performing the step of transferring the product back for stripping.
4. The method according to claim 3 , further comprising a step of raising an alarm when the threshold value is reached.
5. The method according to claim 1 , further comprising a step of detecting a position of the product along the transfer direction.
