Embodiment Construction

[0018] In the present invention, specific reference is made to sewn pockets, which are generally made of thin plastic material, and are therefore of little rigidity when flat, and thus tend to bend when subjected to significant The dimensions between are not constant.

[0019] The valve pocket is elongate with two long sides and two short sides and at least one corner comprising the valve 5 between the long and short sides.

[0020] Between the long and short sides of the pocket there are valves, referred to as the short valve side 6 and the long valve side 7 . The long side opposite the short valve side 6 has the reference numeral 8 and the short side opposite the short valve side 7 has the reference numeral 9 .

[0021] With reference to the accompanying drawings, according to the invention, a device for feeding a stack of bags, for selecting a valve bag and feeding it to the feeding tube of a pocket machine, the device comprises a support frame 10 supporting on one side a ...

Abstract

A sack feeding device for a sacking machine comprising: means (21) for picking up one sack at a time from a stack of sacks arranged on a first plane (11); said sacks being elongated having two long sides (7, 9) and two short sides (6, 8), and at least one corner between a long and a short side comprising a valve (5), said long and a short side with a valve in between being referred to as a short valve side (6) and a long valve side (7); means (32, 34) for pushing one sack at a time so that said long valve side (7) is arranged on a second plane (40) and abuts against a retainer (41) and the long side (9) opposite to said long valve side (7) is contained by a vertical edge (36) opposite to said retainer (41), means (42) for pushing said short valve side (6) to a predetermined position on said second plane (40); means (46) for lifting said short valve side (6), away from said second plane (40).

Description

technical field [0001] The present invention relates to a device for inserting a valve bag into a feed tube of a pocket machine, in particular to a bag feeding device for a pocket machine. The bag is made of paper or plastic, provided with a valve, with or without a gusset bonded, for powdery or granular materials such as concrete and the like. The pocket has a rectangular shape with the valve arranged in the corner between the long and short sides of the pocket. The port of the valve is opened by unfolding the sides and the port is introduced into the feed line of the pocket machine. The pocket machine includes one or more feed inlets for filling the suspended pockets. Pockets are inserted into the feed inlet manually or automatically. Background technique [0002] Automatic machines are known for introducing pockets into the feed inlet, which take one pocket at a time from an aligned stack of pockets. By means of a suitable vacuum cup, the valve is opened and the bag i...
