Abstract

A process and apparatus for producing bag-like packs including a continuous strand (17) which is formed from packaging material folded in a V-shape and having transverse seams (15). Prepared portions (21) of fibrous filling material are pushed into pockets (18), open at the side, during the continuous transporting of the strand (17) by the apparatus. Thereafter, the pockets (18) are closed at a longitudinal seam (16) formed during the continuous transporting. The packs are formed by being severed from the strand (17). The strand (17) and the portions (21) are transported by synchronously running endless conveyors, and specifically by a spreading ring (27) and a portion turret (35), respectively. The above-mentioned conveyors are mounted axially parallel to each other such that, with synchronous running, the portions (21) are pushed radially out of the portion turret (35) into the pockets (18).

Claims18

Dependent claims

A process for producing bag-like packs (10) for housing fibrous filling material, comprising the steps of:

forming a continuous strand (17) of unilaterally open pockets (18) from a web of packaging material, said pockets being separated from one another by transverse seams (15);
filling each of said pockets with a portion (21) of said filling material at a filling zone (32);
closing the pockets with a closure seam extending in a longitudinal direction;
and
severing the closed pockets from the strand (17) in the region of the transverse seams (15) by means of severing cuts, and continuously transporting the portion (21) of the filing material synchronously with corresponding pockets (10) of the strand;
during transport, compressing said portions (21) prior to their being inserted into the pockets (18) such that said portions have a configuration corresponding to the volume of the pockets (18), subsequently the formed portions (21) and the strand (17) with the open pockets (18) are transported synchronously and spaced a predetermined distance apart along said filling zone (32);
and
during transport of the portions (21) and the strand (17) in the region of the filing zone (32), introducing the formed portions (21) into corresponding open pockets (18) by a transverse movement;
and
wherein said portions are transported along a circular transporting path, and during transport the portions (21) are compressed by radially outwardly directed pressure and, in an outwardly directed radial movement, are introduced into respective packs (10) by being pushed into the packs (10) which are conveyed along a coaxial circular path at least during a transfer zone.

7 more elements

An apparatus for producing bag-like packs (10) from two pack walls (11, 12), joined together around the edges thereof, adapted to accommodate portions of fibrous filling material, comprising:

means for forming a continuous strand (17) of packets (18), open at a side, from a web of material (13);
means for filling each of said pockets along a longitudinal seam (16) with a portion (21) of the filling material at a filling zone (32);
means for closing the pockets (18) after said pockets have been filled to form respective packs (10);
means for severing said packs from the strand (17) by severing cuts;
and a continuously driven portion conveyor;
wherein the portions (21) to be packed are transported by said continuously driven portion conveyor into the region of said filling zone (32) at a predetermined distance from the open pockets (18) of the portion conveyor, said apparatus further comprising a pushing member (39), the portions (21) being pushed by said pushing member (39) from the portion conveyor in an outwardly directed movement into the pockets (18);
wherein said portion conveyor comprises a rotatable portion turret (35), the portion turret (35) having a plurality of changers (37), each for receiving a portion (21), the chambers (37) having slide members arranged therein which is moveable in a radial direction, said slide members each comprising a ram (39) having a ram head (38) forming an inner bottom portion of a respective chamber (37);
and
wherein said portion turret includes radial bores (41) formed therein, said apparatus further comprising ram rods (40), wherein said rams (39) are mounted displaceably in the radial direction with the ram rods (40) in the radial bores (41) of the portion turret (35), and wherein said apparatus further comprises at least one of a control cam and a stationary control disc having a control groove (43), the radial movement of the rams (39) being controllable by said at least one of said control cam and said control groove (43) of said stationary control disc (44) such that the rams (39) are selectively movable for filling the portions (21), until in a filling opening (33) of the pockets (18).

6 more elements

An apparatus for producing bag-like packs (10) from two pack walls (11, 12), joined together around the edges thereof, adapted to accommodate portions of fibrous filing material, comprising:

means for forming a continuous strand (17) of pockets (18), open at a side, from a web of material (13):
means for filling each of said pockets along a longitudinal seam (16) with a portion (21) of the filling material at a filling zone (32);
means for closing the pockets (18) after said pockets have been filled to form respective packs (10);
means for severing said packs from the strand (17) by severing cuts;
and a continuously driven portion conveyor;
wherein the portions (21) to be packed are transported by said continuously driven portion conveyor into the region of said filling zone (32) at a predetermined distance from the open pockets (18) of the portion conveyor, said apparatus further comprising a pushing member (39), the portions (21) being pushed by said pushing member (39) from the portion conveyor in an outwardly directed movement into the pockets (18);
wherein said portion conveyor comprises a rotatable portion turret (35), the portion turret (35) having a plurality of chambers (37), each for receiving a portion (21), the chambers (37) having slide members arranged therein which is moveable in a radial direction, said slide members each comprising a ram (39) having a ram head (38) forming an inner bottom portion of a respective chamber (37);
said apparatus further comprising means for compressing said portions (21), said compressing means including said rams (39), wherein before said portions (21) are pushed into the pockets (18), the portions (21) in the chambers (37) are compressed by radial movement of the rams (39) having said ram heads (38) in the outward direction during rotational movement of the portion turret (35).
