PURPOSE:To contrive the improvement in productivity and the decrease of product cost by operating alternatively the unloading and discharging of a product with two unloading means, by providing a pair of unloading means wherein while one means is directed to the position of product gripping, another is directed to the position of product discharging, and by moving pivotally to the reverse directions to each other a rotating shaft which supports integrally and free-rotationally each unloading means. CONSTITUTION:A second unloading means 30 is set up crossly in front view at the required angle, for example 60 deg. as it is directed to the position of product discharging when a first unloading means 20 is directed to the position of product gripping. The product gripper 50' of the second unloading means 30 is fitted on the same axis and in the neiborhood of a cylinder rod 34. On the other hand the gripper 50 of the first unloading means 20 is fitted to a cylinder rod 24 in eccentric relation through a connecting plate 60. The connecting plate 60 is composed of a flat plate in parallelogram form in front view extending to the lower part of the gripper 50 of the second unloading means 30, and a flat plate which is integrally formed at the lower end of the flat plate and extends to the side of the second unloading means 30. Consequently grippers 50, 50' can take the same position of product gripping, therefore interference between them does not occur. |
