Definitions

  • the filled tea bags are brought upright standing on a conveyor and divided into groups of predetermined numbers by means of compartment elements and recorded in rows by the row holder and row slide. After being transferred to the cassette, the row of bags is turned over, shaken and compressed before it is then pushed into the ready box. In this way, the aim is to ensure that the contents of the bag are largely evenly distributed and compressed so that the row of bags fits into the box of a predetermined length provided.
  • Such a device is generally designed for packaging rows of bags of the same size with a predetermined number of tea bags.
  • long changeover times are required, which results in undesirably long machine downtimes.
  • the conditions for obtaining an optimal distribution of the Change the contents of the bag so that there is little time at high machine output to adapt the known device to the changed circumstances. Disruptions in the overall process can therefore hardly be avoided even by such a complex measure as the additional shaking of the tea bags in the cassettes.
  • the row of bags only forms in the stacking shaft by feeding individual bags and keeping them in an upright position at all times between the retaining fingers and the longitudinally displaceable bag holder.
  • an exact separation and fixation of the bags and rows of bags is guaranteed even with high machine performance.
  • the number of bags in a row of bags can be changed as required without the need for any additional measures or changes to the existing components of the device.
  • a constant and largely pressure-free fixation of the bag row is guaranteed, which has a gentle effect on both the tea and the bag goods. This condition remains during the entire packaging process, so that the capacity of the boxes can be used optimally.
  • the device shown schematically in the drawing has a stacking shaft 10 designed in the form of a trough with a rectangular cross section for forming and receiving a row of bags 12 consisting of several filled tea bags 11.
  • the bags 11 are individually separated by means of a tongs-shaped gripping device 13 from an upstream tea packaging machine of a known type (not shown) and transferred to the stacking shaft 10 by means of a bag advancer 14.
  • the gripping device 13 cooperates with a support rail 15 which is arranged in front of the stacking shaft 10 at the level of its lower support surface.
  • two opposing retaining fingers 16 are provided laterally in the entrance area, which are arranged in the longitudinal direction in a stationary manner and resiliently transversely to the longitudinal direction and have an oblique contact surface in the direction of advance of the bags 11.
  • a bag holder 17 is provided which has two arms 18 which are pivotably articulated at 19 on a stationary holder 20.
  • a fork-shaped finger 21 is provided at the free ends of the arms 18 and is attached to the end of a piston rod 22 guided in the arms 18.
  • Arm 18 and piston rod 22 form a piston-cylinder unit, which is preferably connected to a compressed air source, not shown.
  • the arms 18 of the bag holder 17 can be pivoted between a starting position, in which they bear against a stop 23 under spring action, and an end position, which can be changed as a function of the number of bags.
  • additional guide strips 24 are provided on the inside on the side walls of the stacking shaft.
  • a sliding element 25 is fastened, which is set back with its head-side end face relative to the fingertips and, when the fingers 21 are extended, bears against a brake bar 26 on the outer wall of the stacking shaft 10.
  • the brake bar 26 extends approximately over the entire length of the stacking shaft 10 and has one preferably made of plastic sliding surface 27, which is formed in a circular arc shape with respect to the pivot point 19 of the arms 18.
  • the sliding surface 27 is preferably provided with a plurality of transverse grooves 28 which are shaped in width and depth in such a way that the sliding element 25 can easily snap into place.
  • a row holder 29 and a row slide 30 are provided, which are preferably connected to a compressed air source (not shown) and which are in the rest position outside the stacking shaft 10.
  • the row holder 29 is inserted into the stacking shaft 10 against the direction of advance of the bags 11 by means of a piston rod 31, while the counter movement of the row slide 30 is controlled via a lever arrangement 32.
  • the stacking shaft 10 is followed by a rotor designated 33, on which two cassettes 35, 36 arranged diametrically offset from the rotor axis 34 are accommodated (FIG. 4).
  • a cassette 35, 36 In the working position shown in Fig. 1, the cassette 35 is aligned with the stacking shaft 10, while the cassette 36 is in a position in which it is aligned with a transport device consisting of a further row holder 37 and row slide 38, which is preferably also pneumatically actuated is.
  • side holders 39, 40 are provided in pairs, of which the front pair of holders 39 corresponds in structure and operation to the retaining fingers 16, while the rear pair of holders 40 is adjustable in the longitudinal direction.
  • the two pairs of holders 39, 40 hold the row of bags 12 positioned during the rotation of the cassettes.
  • the transport device 37, 38 pushes the row of bags 12 over a box 41, which is positioned on the outlet side of the cassette 36 and above which a pusher 42 is located.
  • the frictional forces of the bag holder 17 to be overcome when loading the stacking shaft 10 are set such that pressure is briefly applied to the row of bags only while a new bag is being added, but otherwise a constant and largely pressure-free fixing of the bags 11 is ensured.
  • the transverse grooves 28 in the brake bar 26 in the region of the initial position of the bag holder 17 ensure that the inadequate internal damping of the row of bags is replaced by an increased resistance in the initial stage of the row formation.
  • the row holder 29 seamlessly takes over the holding of the row of bags 12, so that the bag holder 17 can return to its starting position before reaching the predetermined number of bags per row.
  • the row slide 30 moves behind the last counted bag and pushes the entire row of bags 12 against the friction-damped row holder 29 into a ready-made cassette 35, 36, in which the holders 39, 40 take over the further fixing of the row of bags .
