The device for picking up stacks of products from a support has a head for picking up a stack of products from a supporting platform, and is provided with presser elements for pressing on the stack. The presser elements act in an upward region of the stack and with a flexible lamina that is adapted to fit between the stack and the supporting platform. Additional presser elements are supported by the pick-up head to act on the stack, whereby to take the weight of the stack off the supporting platform and facilitate the insertion of the lamina between the platform and the stack of products.
摘要:
A pickup and feed unit for stacks of blanks, wherein a movable pickup head provides for successively picking up the stacks off a pallet, on which the stacks are arranged and oriented in a given manner, and for feeding them to a receiving member. The head presents a frame oriented in a given manner in relation to the receiving member; and a pickup device with suction cups, rotating in relation to the frame and about a vertical axis, so that the stacks, once picked up, are always oriented the same way in relation to the frame and the receiving member.
