1. A system for removing a packing film from a product having an axis in a longitudinal direction, the packing film being used to pack the product and surrounding lateral portions of the product, wherein a first end of the packing film surrounding a first longitudinal end of the product is open and a second end of the packing film surrounding a second end of the product opposite the first end of the product is closed, the system comprising:
a conveyor configured to carry a plurality of products each packed with a packing film in a direction perpendicular to axes of the plurality of products while supporting the plurality of products such that the axes of the plurality of products are parallel to each other;
a film removal unit comprising a suction unit configured to draw the first end of the packing film in an axial direction of each of the products and a clamping unit configured to clamp the first end of the packing film drawn by the suction unit, wherein the film removal unit is moved in the axial direction of the product between a position in which the film removal unit approaches the product and a position in which the film removal unit is separated from the product so as to remove the packing film from the product; and
a frame on which the conveyor, a support unit, and the film removal unit are disposed,
wherein the suction unit comprises a suction member to which a negative pressure is applied such that the suction member draws the first end of the packing film by approaching the first end of the product, and
the clamping unit comprises a pair of clamping bars disposed on both sides of the suction member to be in contact with or separated from each other in order to clamp the first end of the packing film drawn by the suction unit,
wherein the suction member of the suction unit is configured to move in a direction away from the first end of the product after having drawn the first end of the packing film, and
the pair of clamping bars of the clamping unit are disposed on both sides of the suction member and configured to move backward from positions of the clamping bars by moving in a direction in which the suction member is separated from the first end of the product and then come into contact with each other to clamp the first end of the packing film.
