A process for weighing successive flexible filled packs, without conveyance of the packs being stopped and without the conveyance suddenly decelerating, to weighing device which holds and transports the packs in suspension to a delivery position; the weighing process including measuring by a scale the weight of the assembly formed by the weighing device and the weight of the conveyed pack or packs, the average speed of the conveyance of the packs and/or the length of the conveyed distance being selected such that during a predetermined time period a single pack is held and conveyed in suspension by the weighing device. The weighing device for the packs includes first and second endless belts between which holding portions of the packs to be weighed are introduced, and the suspended packs are conveyed by the movement of the endless belts.

1. A device (1) for weighing successive filled flexible packs provided with a planar end portion (2a), the device comprising: a holding means (3) for the flexible packs to be weighed; anda weighing means (4),wherein the holding means (3) for the flexible packs (2) comprises:first and second endless
1. A device (1) for weighing successive filled flexible packs provided with a planar end portion (2a), the device comprising: a holding means (3) for the flexible packs to be weighed; anda weighing means (4),wherein the holding means (3) for the flexible packs (2) comprises:first and second endless belts (3a, 3b) simultaneously moving forward and describing respective coplanar paths, demarcating between the respective coplanar paths and forward movement sections a space configured to receive insertion of the planar end portions of the successive packs to be weighed,wherein the planar end portions are seized and suspended between the two endless belts (3a, 3b), the flexible packs being conveyed by the movement of the endless belts (3a, 3b) along the forward movement sections of said endless belts (3a, 3b),the weighing means comprising (4) a weight sensor configured to measure weight of an assembly formed by the holding means (3) for the flexible packs, andwherein the holding means is provided with a support means for the conveyed flexible packs, on which the flexible packs slide during the conveyance by endless belts in the weighing device, thereby preventing swinging of said flexible packs while the flexible packs remain suspended from the endless belts. 2. The device (1) according to claim 1, wherein the distance between the support means (5) and the holding means (3) for the packs (2) is adjustable. 3. The device (1) according to claim 1, wherein the holding means (3) for the packs (2) comprise a pair of horizontally arranged and coplanar plates (6a, 6b) suspended from a support structure (7), provided with respective opposite and parallel side edges (8a, 8b) defining a passage (9) for guiding the packs (2) during their conveyance by the endless belts (3a, 3b), and on which there are assembled the respective support rollers (10) of the endless belts (3a, 3b), distributed along their respective forward movement sections. 4. The device (1) according to the claim 3, wherein in a receiving end (A) of the packs (2), each of the coplanar plates (6a, 6b) is provided with a chamfer defining between the coplanar plates a V-shaped recess (11), for guiding and facilitating an introduction of the planar end portion (2a) of the packs (2) to be weighed in the space (4) demarcated by the forward movement sections of the endless belts (3a, 3b). 5. An installation (100) for the weighing of successive filled packs (2), individually conveyed in suspension by conveyor means of an automatic machine (101) for manufacturing and filling packs (2), comprising: a weighing device (1) according to claim 1, supported by a frame anchored to the ground and separate from the frame of the machine (101), the mentioned weighing device (1) being placed adjacent to the machine (101) and such that the path of the packs (2) conveyed by the conveyor means reaches the space demarcated by the forward movement sections of the endless belts (3a, 3b) of the weighing device (1). 6. A process for automatically weighing successive filled flexible packs, the process comprising: providing a weighing device that comprises a conveyor mechanism;delivering a flexible pack to conveyor mechanism;supporting the flexible pack in suspension from the conveyor mechanism and conveying the flexible pack while in suspension by the conveyor mechanism;wherein the flexible pack is supported in suspension from the conveyor mechanism by an upper portion of the flexible pack;stabilizing swinging movement of the flexible pack by having the flexible pack contact a support surface in the weighing device;measuring a weight of the conveyor mechanism and the flexible pack; andreleasing the flexible pack. 7. The process according to claim 6, wherein the flexible pack is suspended from a top end of the flexible pack. 8. The process according to claim 6, wherein the flexible pack slides on the support surface in the weighing device to stabilize the swinging movement of the flexible pack. 9. The process according to claim 6, wherein a bottom end of the flexible pack contacts the support surface. 10. The process according to claim 6, wherein the flexible pack is provided to the weighing device by an upstream conveyor unit that is separate from the conveyor mechanism of the weighing device. 11. A weighing device for weighing successive filled flexible packs provided with a planar end portion, the device comprising: a conveyor mechanism configured to support the flexible pack in suspension by an upper portion of the flexible pack and to convey the flexible pack while in suspension;a support surface positioned to make contact with the flexible pack so as to stabilize swinging movement of the flexible pack;a measuring unit configured to measure a weight of the conveyor mechanism and the flexible pack. 12. The device of claim 11, further comprising the flexible pack in suspension from the conveyor mechanism by a top end of the flexible pack and in contact with the support surface.
