There is disclosed a conveyor for arranging and feeding sheet materials such as plastic bags (2) in a feeding direction, the sheet materials being discharged into a discharge position (4). The conveyor comprises first sprocket or pulley means (10) disposed near the discharge position of sheet material. The conveyor further comprises second sprocket or pulley means (12) disposed downstream of the first sprocket or pulley means in the feeding direction of sheet material. Endless chain or belt means (16) is stretched between the first and second sprocket or pulley means. A plurality of receivers (18) are spaced at a distance from each other along the endless chain or belt means and mounted on and fixed to the endless chain or belt means to extend outwardly of and perpendicularly to the endless chain or belt means, one of the receivers being disposed at the discharge position to receive the sheet materials successively discharged. The receivers are intermittently moved by the endless chain or belt means around the first sprocket or pulley means to feed the sheet materials and make them stand, whenever a number of sheet materials are discharged into the discharge position and stacked on the receiver disposed at the discharge position. In addition, the receivers are intermittently moved by the endless chain or belt means between the first and second sprocket or pulley means to feed the sheet materials with keeping them standing, whenever the number of sheet materials are discharged into the discharge position and stacked on the receiver disposed at the discharge position. <IMAGE> |
