This invention relates to a process and apparatus for packing articles in bags, at a check-out desk of a self-service retail store, for example. It comprises, downstream of said check-out desk, a reserve of bags in the form of a stack of vertically stacked bags, with their side provided with handles and forming the opening, oriented upwardly, means for guiding a bag lying at the top of the stack, from an inactive position against the stack towards an active, open position, separated and detached from the stack, a conveyor lying from a zone plumb with said stack and terminating at an exit station, said conveyor allowing the bottom of the bag to rest thereon when the bag is full of articles introduced through its upper opening, said conveyor being associated with means for controlling its displacement and each face of a bag being connected to the opposite face of the adjacent bag by a detachable point of connection.

An apparatus for packing articles collected together in bags, such as plastic bags with gussets and handles, the apparatus being adapted to equip a check-out and article-evacuating station, such as the check-out desk of a self-service retail store, wherein downstream of said check-out desk, said apparatus comprises: (a) a reserve of bags in the form of a stack of vertically stacked bags, in which each bag is constituted by two faces joined by their bottom and sides and includes upper handles provided with slots for hanging, and each rear face of the first bag is detachably fast with the front face there opposite belonging to the subsequent adjacent bag, by a separable connecting means adapted to yield beyond a determined force of traction of the first bag on the said subsequent bag, the upper side of each bag provided with an opening which includes at least one separable projecting holed lobe element connected to the corresponding upper side of the bag by a line of weakness; (b) means for guiding the successive bags comprising two lateral rods inserted in said slots for hanging, in register from one bag to the other on the whole of the stack, these slots in register being engaged on said rods so that the stack of bags is suspended from said rods such that a first bag at the top of the stack may be displaced from an inactive position against the stack towards a position wherein one face of the bag is separated from the stack, allowing the bag to be brought into an open position and to be filled, and said rods for hanging and guiding the bags are inclined downwardly towards their free end, thus facilitating the sliding motion of the handles of a drawn bag from its storage position towards its open position for filling, the terminal part of each rod being horizontal, thus causing an increase in the resistance opposed to the subsequent sliding motion of the handles along the rods beyond the threshold constituted by the transition of the inclined rods towards the horizontal part, said increase in resistance ensuring that said separable connection means disposed between the rear face of the drawn bag and the front face of the subsequent bag will yield; (c) means for retaining the stack of bags comprising at least one blocking pin inserted in a central hole in said separable lobe element, and including at its end of a lockable catch preventing the stack of lobe elements from escaping; and (d) a conveying means in the form of an endless belt disposed from a zone plumb with said stack and terminating so as to form an exit station, said belt being adapted to receive the bottom of the bag prior to separation from said subsequent bag once said bag is in open position and being filled, such that the bottom of the bag rests on the belt, said belt including mechanical means for controlling the displacement of said belt and ensuring the advance of the bag from its open position for opening said subsequent bag due to said separable connecting means; for separating said bag from said subsequent bag once said subsequent bag is opened and for moving said bag at least concurrent with the separation of said bag from said lobe element towards a position of evacuation at the end of said conveying means.
