Abstract
An apparatus for removing a bag (5) which is open on one side (5) from a stack (2) of such bags which are preferably stored in a bag hopper (1), this being by means of a lifting and suction apparatus, whereby the lifting and suction apparatus is a preferably driven conveyor belt (3) and for further conveying the bag (5) to a position for further processing. In order to enable a high throughput rate of the bags to be removed and to enable the realization of a position for further processing which is variably adaptable to the system requirements or can be optionally horizontal, vertical or in between, it is provided that the lifting and suction apparatus is horizontally and vertically movable to accelerate the removing of the bags.
Claims7
An apparatus for removing a bag from a stack of bags, which comprises an apparatus for lifting the bag from the stack by suction and for conveying the bag in a conveying direction to a position for further processing or filling, the apparatus for lifting and conveying the bag comprising a driven conveyor belt between whose upper and lower strand there is arranged a device for producing a sub-atmospheric pressure for pressing the removed bag against the lower conveyor belt strand, the conveyor belt being driven about two deflection rollers and the two deflection rollers being mounted on two movable arms forming a parallelogram mechanism whereby the two arms convey the conveyor belt from a first position, in which the bag is sucked against the lower conveyor belt strand to the position for further processing or filling, and the conveyor belt and the device for producing the sub-atmospheric pressure is held horizontally and vertically movable to accelerate the removing of the bag.
